The topic 4 one-minute changes you can make to your PC that will improve its performance is currently the subject of lively discussion — readers and analysts are keeping a close eye on developments.
This is taking place in a dynamic environment: companies’ decisions and competitors’ reactions can quickly change the picture.
PC performance comes down to more than just a few small tweaks, but there are small setting changes that can make a big difference to your system’s ability to churn out frames or blaze through productivity tasks. None of the items on this list are asking you to set aside a weekend to completely reinstall your OS, repaste your CPU and dust out your computer, but instead, they’re changes that take one or two clicks that give a noticeable bump in FPS, clean up frametimes and latency, and make your system feel a bit snappier overall.
This is the number-one most suggested tweak you’ll see on every list, and that’s for good reason, because a surprising amount of PC owners either skipped it when they built their rig, it got turned off in a BIOS update or CMOS clear, or if the PC was prebuilt, it wasn’t turned on to begin with.
RAM ships running at JEDEC baseline speeds, which is typically DDR5-4800 or DDR4-2133. Even if you bought faster RAM, until you enable the XMP/EXPO profile, you’ll be running on those stable JEDEC speeds. On Ryzen systems especially, memory speed has an big effect on 1% lows and overall gaming performance thanks to how Infinity Fabric scales with memory clock. You’ll find the toggle under whatever your board calls its overclocking tab, which could be “AI Tweaker,” “OC,” or “Extreme Tweaker.” Intel boards label the profile “XMP,” AM5 boards use “EXPO”, and it can sometimes be found on the main splash page of your BIOS.
While it’s on by default on most new builds, it’s still one that gets missed on older systems. Resizable BAR lets the CPU access the full GPU frame buffer in one go rather than in 256 MB chunks, and on modern GeForce and Radeon cards it’s free performance in supported titles. The uplift varies a bit. It could improve framerates by 10%, other games see no improvement, but there’s no downside to having it on.
Enabling it requires UEFI boot with CSM disabled, which trips people up on older installs. Once the BIOS toggle is flipped, verify it actually took effect in GPU-Z or your GPU control panel rather than trusting the BIOS alone, as I’ve seen cases where the setting was enabled but not actually active.
Don’t want to spend? No problem. You can boost your FPS for free with these tips
I can’t tell you how many times I’ve heard complaints from family or friends that their PC feels slow during gaming. Windows has a long-running habit of defaulting high-refresh monitors to 60 Hz after driver updates, display swaps, or cable changes, and a lot of people are running 144 Hz or 240 Hz panels at a fraction of their capability without realizing it.
Advanced display and confirm the refresh rate matches what your panel is actually rated for. While you’re there, flip on VRR if you consistently run under your monitor’s refresh rate in certain games. For G-Sync or FreeSync users, a quick check in the Nvidia Control Panel or Adrenalin confirms VRR is actually active at the driver level rather than just enabled in Windows.
While it sounds a bit counter-intuitive, setting a cap on your FPS will improve frametime consistency and lower end-to-end latency, and in titles where your FPS exceeds your monitor’s refresh rate, this can make things feel a lot smoother.
On a VRR display, capping your framerate three to five FPS below your monitor’s maximum keeps the framerate inside the VRR window and prevents the tearing and stutter that happens when frames exceed the panel’s ceiling. Even on displays that don’t have VRR, an uncapped framerate pushes the GPU to 99–100% utilization, which backs up the render queue and increases input latency. A cap that keeps the GPU at around 90–95% utilization often reduces latency despite the lower raw FPS number, and in specific games, doing so at the driver level can be more beneficial, but your mileage may vary.
These aren’t going to be cure-all fixes for bad performance, but they’re things you can do to make sure you’re getting the performance out of the components you paid for. Stacked together, the difference is genuinely noticeable. Games feel smoother, input latency drops, and the system stops doing the small, annoying things that make a PC feel slower than it actually is.
