Before you spend $500 on a new graphics card, spend twenty minutes in your settings menus. Most gaming PCs are running well below their real potential because of one outdated driver, one forgotten background app, or a handful of graphics settings that cost a lot of frame rate for almost no visual payoff. This guide walks through every free way to optimize PC gaming performance, in the order that actually moves the needle, from driver housekeeping to the Windows power settings almost nobody checks. We put these steps to use ourselves whenever a system feels sluggish before recommending anything at Bralad.com, and they consistently recover real, measurable FPS without spending a dollar.
Update Your Graphics Drivers the Right Way
An outdated or corrupted graphics driver is the single most common cause of poor PC gaming performance, and it’s the first thing to rule out. NVIDIA users should install the NVIDIA app (the successor to GeForce Experience) and check for the latest Game Ready driver; AMD users should do the same through AMD Software: Adrenalin Edition. Both check for updates automatically, but it’s worth manually checking after a major new game launch, since publishers often ship Game Ready or Day-0 drivers timed to release day.
If you’ve swapped graphics cards recently or a driver update introduced a new problem, a clean installation resolves far more issues than a standard update. Use the driver software’s built-in clean-install option, or a dedicated uninstaller tool, to fully remove old driver files before installing the new version rather than just installing over the top.
It’s also worth checking Device Manager occasionally (right-click the Start button and select it) to confirm Windows itself isn’t quietly using a generic driver instead of the manufacturer’s version, which can happen after a Windows Update. Look under Display Adapters — if the driver date is older than a few months or the name looks generic rather than branded NVIDIA or AMD, reinstalling through the official app fixes it in a couple of minutes.
In-Game Settings That Actually Matter
Not all graphics settings cost the same. Shadows, ambient occlusion and ray-traced reflections are consistently among the most expensive settings in any modern game relative to how much they visibly improve the picture, especially at a normal viewing distance from a monitor. Dropping shadow quality from Ultra to High or Medium routinely recovers 10-20% more frame rate while being almost impossible to notice mid-gameplay.
Texture quality is the opposite case: it’s cheap on frame rate as long as you have enough graphics memory (VRAM) to hold the higher-resolution textures, and it has an outsized effect on how sharp the game looks up close. Keep texture quality high and save your frame rate budget by lowering shadows, motion blur, depth of field and any “ultra” post-processing effects first — those are the settings built to impress screenshots, not gameplay.
DLSS, FSR and Frame Generation Explained
Upscaling technology is the biggest free performance win available on a modern gaming PC, and it works by rendering the game at a lower internal resolution before using software to reconstruct a sharper image at your display’s native resolution. NVIDIA’s version, DLSS, uses AI processing built into RTX-series graphics cards and includes Frame Generation on newer cards, which inserts extra AI-generated frames between rendered ones to push frame rates even higher.
AMD’s FidelityFX Super Resolution (FSR) does a similar job without requiring specific hardware, which is why it also shows up on non-NVIDIA gaming handhelds like the Steam Deck and ROG Ally, covered in our gaming handhelds guide. Intel’s XeSS is a smaller third option worth knowing if you’re running an Intel Arc graphics card. Whichever your GPU supports, turning on the “Quality” or “Balanced” upscaling mode in a game’s graphics menu is often worth more frame rate than every other individual setting change combined.
Windows Settings That Free Up FPS
Windows runs a surprising number of background processes and visual effects that quietly compete with your game for CPU time and memory. Start with Settings > System > Power & battery > Power mode, and set it to Best Performance while gaming on a desktop, or plugged in on a laptop — the balanced default deliberately throttles performance to save power.
Next, check Settings > Gaming > Game Mode is switched on, which tells Windows to prioritize your game’s process over background tasks automatically. The Xbox Game Bar overlay (Windows key + G) is useful for quick recording but can cost a few frames per second when it’s actively running in the background, so close it when you’re not using it. Finally, open Task Manager (Ctrl+Shift+Esc), sort by CPU or memory usage, and close anything you don’t recognize or need — browser windows with dozens of tabs open are a frequent, easily fixed culprit.
Startup programs are worth a separate pass. Still in Task Manager, click the Startup Apps tab and disable anything you don’t need running the moment Windows boots — chat clients, cloud sync tools and launcher auto-updaters are common offenders that quietly eat memory and CPU cycles for hours before you ever open a game. Storage Sense, under Settings > System > Storage, is also worth turning on so temporary files don’t slowly fill your drive between manual cleanups.
GPU Control Panel Settings Worth Changing
Both NVIDIA and AMD bury a few genuinely useful settings inside their control panels. In the NVIDIA Control Panel, under Manage 3D Settings, setting Power Management Mode to “Prefer Maximum Performance” stops the card from downclocking between frames in less demanding scenes, and enabling Low Latency Mode (Ultra) reduces input lag noticeably in competitive games.
AMD Software: Adrenalin Edition has an equivalent Radeon Anti-Lag feature under the Gaming tab, plus a Radeon Boost option that dynamically lowers resolution during fast camera movement, when you’re least likely to notice, then restores it when you slow down. Both companies’ software also lets you create per-game profiles, which is worth doing for anything you play regularly so your changes don’t apply globally to games that didn’t need them.
Monitor and Display Settings
A powerful graphics card capped by a mismatched monitor is one of the most common bottlenecks we see. Check Settings > System > Display > Advanced display and confirm your monitor is actually running at its full refresh rate — it’s common for a 144Hz or 165Hz monitor to default back to 60Hz after a cable swap or driver update without any obvious warning.
If your monitor supports G-Sync (NVIDIA) or FreeSync (AMD), enable it in both the monitor’s own settings menu and the graphics control panel; it synchronizes the display’s refresh rate to the game’s frame rate and eliminates the tearing you’d otherwise get from a mismatch. HDR can also quietly cost frame rate in some games when enabled system-wide but unused by the specific title you’re playing, so it’s worth testing with it off if a game feels less smooth than expected.
Cooling and Storage: The Overlooked Performance Factors
Thermal throttling is a quiet performance killer that never shows up as an error message. When a CPU or GPU runs too hot, it automatically lowers its own clock speed to protect itself, which shows up in-game as inconsistent frame rates that dip during longer sessions rather than a hard crash or warning. Compressed air through the intake and exhaust fans every few months, especially in a desktop that sits on carpet or shares a room with pets, recovers real performance for free and costs a few dollars at most.
Storage matters more than most players expect, too. A game installed on a mechanical hard drive loads noticeably slower than the same game on a solid-state drive, and in open-world titles a slow drive can even cause textures to visibly pop in as you move through the environment. If you’re still running your most-played games from a hard drive, moving just two or three of them to an SSD, even a budget model, is one of the more noticeable upgrades available for modest money. Check free space while you’re at it: Windows and modern games both perform worse when a drive is nearly full, since there’s less room left for temporary files and virtual memory.
Bralads tip: Change one setting at a time and note the difference before moving to the next. Bundling five changes together makes it impossible to know which one actually helped, and some — like disabling Game Mode — can occasionally hurt performance on specific hardware.
Settings Priority: What to Change First
| Change | Typical FPS Impact | Visual Impact |
|---|---|---|
| Enable DLSS/FSR upscaling | High | Minimal at Quality mode |
| Update graphics driver | Varies, sometimes large | None |
| Lower shadows/ambient occlusion | Medium-High | Low |
| Set Power Mode to Best Performance | Medium | None |
| Close background apps | Low-Medium | None |
| Lower texture quality | Low (if VRAM-limited: High) | Medium-High |
| Enable Radeon Anti-Lag/NVIDIA Low Latency | Low (helps input feel, not FPS) | None |
Networking and Latency for Online Games
Frame rate isn’t the only performance metric that matters in competitive online games; ping and packet stability matter just as much. A wired Ethernet connection is still meaningfully more consistent than Wi-Fi for anything competitive, even a fast one, because wireless connections are more prone to brief interference spikes.
If Ethernet genuinely isn’t practical in your setup, a modern router helps close the gap — our Wi-Fi 7 explainer covers what the newest wireless standard actually improves versus older Wi-Fi generations, and whether upgrading your router is worth it for gaming specifically. Either way, restart your router occasionally and keep game clients and Windows itself updated, since patches frequently include networking stability fixes alongside the features you actually notice.
When Free Tweaks Aren’t Enough: Hardware Bottlenecks
Settings changes have a ceiling. If your CPU is several generations old, or your graphics card doesn’t have enough VRAM for the resolution and texture quality you want, no amount of software tuning fully closes that gap. Task Manager’s Performance tab is a decent free diagnostic: if your GPU sits near 100% usage while your CPU is well below that, you’re GPU-bound and should prioritize lowering GPU-heavy settings; the reverse points to a CPU bottleneck instead.
If you’ve worked through every setting here and performance is still disappointing, it may genuinely be time to consider new hardware. Our gaming PC vs console comparison and our roundup of gaming accessories worth buying both cover where extra money is actually well spent — often a monitor or a mouse matters more to how a game feels than another GPU tier.

Frequently Asked Questions
Will updating my graphics driver really improve FPS?
Often yes, especially after a new game launch, since driver updates frequently include game-specific optimizations. Occasionally a new driver introduces its own bug, which is why keeping the previous version’s installer handy for a quick rollback is good practice.
Does closing background apps actually make a noticeable difference?
It depends on what’s running. A handful of browser tabs and a chat app barely register, but streaming software, other games, or heavy sync tools like cloud backup clients can meaningfully compete for CPU and memory while you’re gaming.
Should I use DLSS or FSR even if my PC can already hit high frame rates?
It’s still worth testing. Beyond raw frame rate, upscaling reduces GPU load and heat, which can mean quieter fans and more consistent performance during long sessions, even if you don’t strictly need the extra frames.
Is it better to lower resolution or lower settings for more FPS?
Lowering individual settings, especially shadows and post-processing, usually preserves more visual sharpness per frame rate gained than dropping resolution outright. Save resolution as a last resort, or lean on DLSS/FSR instead, which effectively does a smarter version of the same thing.
Do these tweaks work on a laptop the same way as a desktop?
Mostly yes, with one addition: check that your laptop is set to use the dedicated graphics card rather than integrated graphics for your games, usually found in the same NVIDIA or AMD control panel under graphics preferences.
Is overclocking worth it for more FPS?
It can help, but it’s the last step, not the first. Overclocking a CPU or GPU squeezes out extra clock speed beyond factory settings, typically a modest single-digit percentage gain, and it adds heat and complexity that isn’t worth the risk until every free software setting in this guide is already handled.
Bottom Line on Optimizing PC Gaming Performance
Most PCs have meaningful free performance sitting untouched in a driver update, a Windows power setting, or an upscaling toggle nobody turned on. Work through this guide roughly in order — drivers and upscaling first, individual graphics settings second, and Windows housekeeping alongside both — before spending money on new hardware.
If you’ve done all of this and performance still disappoints, that’s a genuine signal your hardware has hit its ceiling, not a sign you missed a setting. For more practical, no-nonsense PC guides like this one, browse the rest of the gaming section at Bralads.
