How to optimize your PC for gaming: the complete checklist
26 October 2026 · ~8 min read
Most "optimize your PC for gaming" lists are either a random grab-bag of tips with no sense of which ones actually matter, or a single tool's marketing page. This is neither - it's the real order of operations we'd actually work through to optimize a PC for gaming on Windows 10 or 11, biggest confirmed impact first, with the honest impact level for each step and a full dedicated guide linked for every one. Every step below maps to a real, specific tweak, not a vague instruction to "clean up your PC."
1. Background processes and startup clutter
The most reliably real win, and the first place to actually optimize, not the most exotic. Launchers, updaters, and chat apps defaulting to running constantly compete with your game for the same CPU and RAM the moment it launches. See our full guide to reducing background processes on Windows 10 and 11 for which ones are genuinely safe to close and which are disguised as something load-bearing.
2. GPU driver settings
Your graphics driver's own control panel has real, GPU-specific levers: Low Latency Mode, power management mode, and shader cache size on NVIDIA, or Anti-Lag and Radeon Chill on AMD. This is a genuinely high-impact, low-risk step most people skip entirely because it isn't inside the game itself.
3. CPU core and device affinity
Pinning cores and isolating device interrupts is real for some games and folklore for others - it depends entirely on whether the engine is a legacy single-threaded one or a modern multi-threaded one. Full evidence-based breakdown in our CPU core affinity guide, and the actual classification for 100+ specific titles in our games affinity database.
4. RAM and memory
A genuinely free FPS gain a lot of PCs are leaving on the table: RAM runs at a slow default speed until you turn on XMP or EXPO in BIOS. Full breakdown of this and dual-channel configuration in our RAM and memory settings guide.
5. GPU scheduling and frame pacing
Hardware-Accelerated GPU Scheduling is real, low-risk, and genuinely helps 1% lows and latency on most modern setups - with two documented exceptions worth knowing first (legacy engines, VRAM-constrained cards). Full data in our HAGS guide.
6. Network: the layer most "PC optimization" advice skips
A perfectly optimized PC still feels laggy online if your connection spikes under load. This is bufferbloat, a genuinely different problem to raw latency, with a genuinely different fix - see our bufferbloat test guide.
7. Display and input devices
The last link in the chain: refresh rate, overdrive, and VRR range on your monitor, plus polling rate, DPI, and acceleration on your mouse and keyboard. Each adds a real, individually small amount of delay that compounds with everything above it.
8. In-game settings, per title
Generic advice ("turn everything down") misses settings that are genuinely specific to one engine - Fortnite's Performance Mode, or Valorant's built-in NVIDIA Reflex, aren't choices a universal PC optimization pass would ever surface. See our Fortnite and Valorant optimization guides for two worked examples.
What to skip entirely
A short, real list of advice that keeps getting repeated across this whole space without holding up: disabling CPU idle states (see our C-States guide), applying every registry tweak a tool lists without checking which category it falls into (see our registry tweaks guide), and trusting a tweak count as a proxy for quality (see our guide to choosing a tweaking tool).
How to check your PC optimization actually worked
Apply one change, measure real frame times before and after against a game you actually play, 1% lows included, not just the average - a spike-y, stuttery game can still average fine on paper. This is exactly what GoldCore's own Tweak Verification Lab automates: a real baseline, the tweak applied, a second measurement in the same session, both numbers reported honestly.
Frequently asked
What's the right order to optimize a PC for gaming?
Fix the biggest confirmed cost first, not whatever's easiest to change. For most PCs that's background process load and driver-level GPU settings, then CPU core/device affinity, then RAM and storage, then network and display. A small tweak at the bottom of that order rarely matters if a bigger one above it is still unaddressed.
Do I need to pay for a PC optimizer to do this?
No - almost every step here is a free Windows, driver, or in-game setting you can change yourself with no software at all. A PC optimizer's real value is organizing these into one place, explaining what each one actually does, risk-rating them, and letting you revert cleanly - not unlocking settings that were otherwise hidden or paywalled by Windows itself.
How do I know a PC optimization step actually worked?
Measure real frame times before and after each individual change against a game you actually play, 1% lows included, not just the average. Changing several settings at once and seeing a number improve doesn't tell you which one mattered, or whether any of them did.
