War Thunder Crashing and Low FPS: Fixes That Work

War Thunder crashing mid-match or crawling at low FPS is usually a resources-and-settings problem, not a broken game. This guide covers the fixes that actually move the needle, starting with the most common crash cause.

1. “Not enough memory” / out-of-memory crashes

This is the classic War Thunder crash, and it is almost always about RAM or texture settings, not a game bug.

• Lower texture quality — the biggest memory consumer. Drop it one step; the crash often disappears.
• Close background apps — browsers with many tabs, Discord, recording tools, and RGB software eat RAM War Thunder needs.
• Check your RAM — War Thunder’s memory floor has risen. 8 GB is tight; 16 GB is comfortable. If you are at the limit, closing everything else is mandatory.
• 32-bit client — if you are somehow on an older 32-bit build, it caps addressable memory; use the 64-bit client.

2. Graphics settings for stability over looks

• Turn shadows and anti-aliasing down first — they cost the most for the least gameplay value.
• Disable depth of field, motion blur, and vignette — pure cost, no benefit in a competitive sim.
• Set vehicle and environment quality to match your GPU, not max.
• The controls and settings guide covers the client options in more detail.

3. Drivers and the client

• Update GPU drivers — stale drivers cause both crashes and stutter.
• Verify game files (Steam: Properties → Installed Files → Verify; standalone launcher has a built-in check). Corrupted files crash unpredictably.
• Run as administrator if crashes persist on launch or during load.

4. Laptops with two GPUs

The integrated GPU is the default for many laptops, and War Thunder on it means terrible FPS or crashes from shared memory.

• Force War Thunder to use the dedicated GPU in Windows Graphics Settings (or the NVIDIA/AMD control panel).
• Plug in the charger — many laptops throttle the dGPU on battery.

5. Overheating

Sustained crashes after 10–20 minutes often point to heat. Clean vents, lift the laptop for airflow, or cap the frame rate to reduce load.

Stability is mostly texture quality + RAM headroom + the right GPU. Fix those three and the crashes usually stop. Once stable, the common beginner mistakes page helps you stop losing for gameplay reasons instead of technical ones.
