Whether your gaming PC is struggling with low frame rates or you simply want to squeeze more performance out of your existing hardware, knowing how to improve FPS in games is an essential skill for PC gamers. Many FPS improvements require zero hardware upgrades — software optimizations, driver settings, and Windows tweaks can deliver 20–50% performance improvements before you spend a dollar on new parts.

Outdated GPU drivers are one of the most common causes of poor gaming performance. NVIDIA and AMD release optimized drivers for new game launches that can improve performance by 5–15% in specific titles. Download the latest drivers from nvidia.com/drivers or amd.com/support. Use DDU (Display Driver Uninstaller) in safe mode for a clean driver installation if you’re experiencing instability.
2. Enable XMP/EXPO for Your RAM
Most gaming PCs ship with RAM running at JEDEC default speeds (DDR4-2133 or DDR5-4800), far below the kit’s rated speed. Enabling XMP (Intel) or EXPO (AMD) in BIOS boosts RAM to its rated speed (DDR4-3200, DDR5-6000, etc.) — a free 5–15% gaming performance improvement on AMD platforms where RAM speed directly affects gaming frame rates.
3. Use Game Mode and Hardware-Accelerated GPU Scheduling
Windows 11’s Game Mode allocates CPU and GPU resources to the active game, reducing background process interference. Enable it in Settings → Gaming → Game Mode. Hardware-Accelerated GPU Scheduling (HAGS) in Settings → Display → Graphics can reduce latency in supported games. Both are free, no-downside performance toggles.
4. Adjust In-Game Graphics Settings
Not all settings impact performance equally. The highest-impact settings to reduce for FPS gains: Resolution Scale/DLSS/FSR (biggest impact), Shadow Quality (significant GPU cost), Ambient Occlusion, Volumetric Fog, and Anti-Aliasing. The lowest-impact settings you can keep high: Texture Quality (VRAM-limited, not GPU performance), Anisotropic Filtering, and LOD Distance.
5. Enable DLSS, FSR, or XeSS Upscaling
AI upscaling technologies are the single biggest FPS improvement available to modern GPUs. DLSS 3 (NVIDIA RTX) in Quality mode delivers near-native visual quality at 50–70% higher frame rates. FSR 3 (AMD, works on any GPU) in Quality mode provides 40–60% FPS gains. Enabling upscaling in a demanding title can double your frame rates with minimal visual quality loss.
6. Set Your Power Plan to High Performance
Windows often defaults to “Balanced” power mode, which throttles CPU frequency to save power. Right-click the battery icon → Power Options → High Performance. On desktop PCs, enable “Ultimate Performance” via PowerShell: `powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61`. This ensures your CPU runs at maximum frequency during gaming.
7. Close Background Applications
Chrome, Discord video, antivirus scanning, cloud sync services, and Windows Update can consume significant CPU and RAM bandwidth during gaming. Close unnecessary applications before gaming sessions. Use Task Manager to identify high CPU/RAM consumers. Consider suspending antivirus real-time protection (temporarily) during gaming if it causes stuttering.
8. Monitor Your Temperatures
CPU and GPU thermal throttling reduces clock speeds to prevent damage when temperatures exceed safe limits. Use HWiNFO64 or MSI Afterburner to monitor temperatures during gameplay. GPU over 90°C: clean dust from fans and heatsink, improve case airflow, consider repasting GPU. CPU over 95°C: check cooler mounting, replace thermal paste, improve case airflow.
9. Optimize NVIDIA/AMD Driver Settings
NVIDIA: In NVIDIA Control Panel, set “Power Management Mode” to “Prefer Maximum Performance,” enable “Low Latency Mode” = Ultra for competitive games, and set “Texture Filtering Quality” to Performance. AMD: In Radeon Software, enable Radeon Anti-Lag, set “Texture Filtering Quality” to Performance, and enable Enhanced Sync for tearing reduction without full V-Sync latency.
10. Upgrade Your Storage (If Using HDD)
Gaming on a hard drive (HDD) causes extended load times and micro-stutters during open-world streaming. Upgrading to an NVMe SSD dramatically improves load times and reduces in-game stutter in open-world games. Direct Storage technology in Windows 11 further accelerates asset loading on NVMe drives. This is the highest-impact upgrade for systems still running spinning drives.
11. Increase Virtual Memory (Page File)
If you have 16GB RAM or less, increasing Windows page file size prevents out-of-memory crashes in VRAM-hungry titles. Set the Custom Size manually (Initial: 1.5× your RAM in MB, Maximum: 3× your RAM in MB) on your fastest drive. This doesn’t replace physical RAM but prevents catastrophic performance drops when RAM is exhausted.
12. Use a Wired Network Connection
Wi-Fi introduces latency variability (jitter) that causes online game stuttering even when average ping is low. A direct Ethernet connection provides stable, low-jitter connectivity. If running cable isn’t feasible, a powerline adapter or gaming Wi-Fi 6E router significantly reduces jitter compared to standard Wi-Fi.
13. Reinstall or Verify Game Files
Corrupted game files cause stuttering, crashes, and performance degradation. Steam: Right-click game → Properties → Local Files → Verify Integrity. Epic Games: Library → three dots → Verify. This re-downloads only corrupted files and often resolves persistent performance issues.
14. Overclock Your GPU (Advanced)
Using MSI Afterburner, you can safely overclock your GPU’s core clock (+50–150 MHz) and memory clock (+200–500 MHz) for 5–15% additional performance. Increase in small increments, run stability tests between adjustments, and monitor temperatures. Most modern GPUs have safe thermal headroom for moderate overclocks.
15. Upgrade Hardware When Software Optimizations Are Exhausted
If software optimizations are implemented and you’re still CPU or GPU limited, hardware upgrades are the next step. GPU upgrade provides the highest FPS return per dollar. Adding RAM (8GB → 16GB) eliminates memory-limited stuttering. CPU upgrades help primarily in CPU-bottlenecked scenarios (high FPS competitive games at low settings).
Frequently Asked Questions
Why is my FPS so low on a good PC?
Common causes: CPU bottleneck (GPU not fully utilized), RAM running at default speed (XMP not enabled), thermal throttling, background applications consuming resources, or outdated drivers. Use MSI Afterburner to monitor GPU usage — if it’s below 95% in-game, you have a CPU bottleneck or other resource constraint.
Does more RAM improve FPS?
Going from 8GB to 16GB eliminates RAM-limited stuttering in modern games significantly. Beyond 16GB, additional RAM provides minimal gaming performance gains. Faster RAM (enabled via XMP) improves AMD gaming performance noticeably; Intel shows smaller gains from RAM speed.
What causes FPS drops during gaming?
FPS drops (as opposed to consistently low FPS) are typically caused by thermal throttling, background processes spiking, shader compilation stutters (especially on NVIDIA in new games), insufficient VRAM causing disk streaming, or driver bugs. Monitor resource usage with HWiNFO during gameplay to identify the culprit.
