How to Boost FPS in Valorant and CS2 on Low-End PC (2026 Guide)
Why High FPS Matters for Competitive Gaming
Frame rate directly impacts aim performance in two ways:
- Input lag: At 60 FPS, each frame takes 16.7ms. At 240 FPS, each frame takes 4.2ms. Lower frame time = your mouse movements register on screen faster.
- Visual smoothness: Moving enemies appear smoother at higher FPS, making them easier to track and click.
The competitive minimum for ranked play: 144 FPS. The competitive target: 240+ FPS. Both Valorant and CS2 are CPU-limited games — which is good news for budget builds.
Valorant FPS Optimization (2026)
In-Game Settings (Valorant)
Expected FPS Gains (Valorant)
| Hardware | Before Optimization | After Optimization |
|---|---|---|
| Ryzen 5 3600 + GTX 1060 6GB | 90–120 FPS | 180–240 FPS |
| i5-10400F + RTX 2060 | 180–220 FPS | 280–350 FPS |
| Ryzen 5 5600X + RTX 3070 | 300–380 FPS | 400–500 FPS |
CS2 FPS Optimization (2026)

In-Game Settings (CS2)
Windows Optimization for FPS Games
NVIDIA-Specific: NVIDIA Reflex
Enable NVIDIA Reflex + Boost in both Valorant and CS2. This optimization reduces system latency (the delay between your mouse movement and the frame rendering the result) by 10–25ms. It is the single most effective software optimization for competitive FPS.
Hardware Upgrades: Best ROI for FPS Games
| Upgrade | FPS Impact | Approx Cost |
|---|---|---|
| RAM: 8GB → 16GB DDR4 | +15–30% in CPU-limited games | $30–50 |
| HDD → SSD (game drive) | No FPS gain, but eliminates stutters | $40–60 |
| CPU: i5-9400F → Ryzen 7 5700X | +40–60% in CS2/Valorant | $150–200 |
| 144Hz → 240Hz monitor | No FPS change, but major feel improvement | $150–250 |
After optimizing your FPS, verify your sensitivity hasn't been accidentally altered in the process using our eDPI calculator — some optimizations reset game config files.
