GTA 5 is one of the most popular open-world games of all time, but it can be very demanding on low-end PCs. Players with 2GB RAM, 4GB RAM, or even 8GB RAM systems often face lag, stutters, or very low FPS, making the game difficult to enjoy. The good news is that with the right tweaks and optimizations, you can boost FPS and fix lag even on older PCs.
Why GTA 5 Lags on Low-End PCs
The main reason GTA 5 struggles on low-spec systems is because of limited RAM, weak GPUs, and processors that can’t handle the high level of detail in the game. By default, GTA 5 uses heavy graphics settings like high textures, shadows, grass quality, and draw distance. On 2GB or 4GB RAM PCs, these settings push the system beyond its limit, causing lag and stutter.
How To Fix Lag & Boost FPS (Step by Step)
- Lower all in-game graphics settings to Normal or Low.
- Turn off V-Sync and set resolution to 720p for smoother gameplay; Click Here
- Use DirectX 10 instead of DirectX 11 for better performance on low-end GPUs.
- Install GTA 5 Low-End PC Config Files (available on modding sites).
- Use commandline.txt tweaks (add lines like -nomemrestrict, -norestrictions, -availablevidmem 4000).
- Set GTA 5 to High Priority in Task Manager.
- Disable background apps (Chrome, Discord, antivirus scans, etc.) while gaming.
- Defragment your HDD or install GTA 5 on an SSD for faster loading.
- For 2GB RAM PCs, use a RAM booster tool or ReadyBoost (USB as virtual RAM).
- Update GPU drivers to the latest version for maximum compatibility.
Conclusion
With these optimizations, you can fix lag and significantly boost FPS in GTA 5 even on a low-end PC. Whether you’re running with 2GB, 4GB, or 8GB RAM, the right settings can transform your experience and make the game much more playable. While you won’t get ultra graphics, you’ll still be able to enjoy Los Santos without annoying stutters and freezes.
