Fix GTA 4 Fps lags and Boost FPS

GTA 4 is one of the most popular games in the Grand Theft Auto series. However, the PC version is badly optimized. Many players face lag, stuttering, and FPS drops, especially on low-end PCs. If you have no graphics card and only 2GB RAM, the game can feel almost unplayable.

This guide explains a working GTA 4 lag fix using DXVK and the right graphics settings. With this method, GTA 4 can run smoothly even on weak systems.

Why GTA 4 Lags on PC

The main reason GTA 4 lags on PC is poor optimization. Even when the FPS looks fine, the game often feels choppy.

Main reasons for lag:

• GTA 4 uses DirectX 9, which does not work well with modern hardware
• Frame timing is unstable, which causes small stutters
• The game does not correctly detect VRAM, so performance is limited

Because of this, players experience stuttering while driving, sudden FPS drops, and slow response. Lowering graphics alone does not fully fix the problem.

GTA 4 DXVK Lag Fix (Big FPS Boost)

DXVK is one of the best fixes for GTA 4 lag. It converts DirectX 9 to Vulkan, which helps the game use your hardware more efficiently, even integrated graphics.

With DXVK:

• FPS becomes much more stable
• Stuttering is greatly reduced
• Performance improves while driving and during heavy action

Many users report FPS increasing from unstable 50–60 to smooth 90–140+, depending on the situation.

How to Install DXVK for GTA 4

Follow these steps carefully:

1. Download the latest DXVK version from the official GitHub page (link is in the video description)
2. Extract the downloaded .gz file using 7-Zip
3. Open the extracted .tar file
4. Open the x32 folder
5. Copy all files from the x32 folder
6. Paste them into your GTA 4 main game folder (where GTAIV.exe is located)

Optional but helpful:

• Use bug-fix or downgrade mods for GTA 4
• Use RivaTuner Statistics Server (RTSS) to lock FPS

DXVK changes how GTA 4 renders graphics, which reduces CPU load and removes stuttering.

Best GTA 4 Graphics Settings for Low-End PC

Even with DXVK, graphics settings are important. These settings give good performance without making the game look bad.

Recommended settings:

• Resolution: Choose what fits your screen
• Aspect Ratio: Auto
• Texture Quality: High
• Reflection Resolution: High
• Water Quality: Low
• Shadow Quality: Medium or High
• Night Shadows: Off
• Texture Filter: Anisotropic x8 or lower
• View Distance: 50
• Detail Distance: 50
• Vehicle Density: 50
• VSync: Off

These settings help reduce lag and make gameplay smooth, even with 2GB RAM and no GPU.

Why You Should Lock FPS in GTA 4

DXVK can push very high FPS, but unstable FPS can still cause stutter. Locking FPS gives smoother gameplay.

Best option:

• Lock FPS to 60 using RivaTuner Statistics Server

A stable 60 FPS feels much smoother than FPS jumping between 80 and 140.
