Why does my game crash on certain GPUs?

Because GPUs and their drivers vary enormously in capabilities and behavior, so your code can hit a difference that only certain hardware exposes: a shader one GPU runs fine that crashes another, a feature some GPUs lack, a driver bug, or a VRAM limit. These GPU-specific crashes won't reproduce on your machine if it has different hardware. Capturing crashes tagged by GPU from real players reveals which GPUs crash, pointing at the driver or feature issue behind it.

How do I fix GPU crashes I can't reproduce?

Capture the crashes tagged by device and GPU, and look at the hardware pattern, all on one GPU family or a certain driver points at the cause. Then address it: reduce VRAM usage, fix or guard problematic shaders (provide a fallback on affected GPUs), supply alternatives for unsupported features, or handle device-lost events gracefully. You fix GPU crashes from the hardware pattern in the captured data, not by reproducing them, since you likely lack the affected GPU.

What Causes GPU Crashes?

Q: What causes GPU crashes?

GPU crashes come from problems in rendering: running out of video memory (VRAM) from too many or too large textures and buffers, shaders the GPU can't compile or run correctly, driver bugs, device-lost or device-removed events (the GPU resetting from a timeout or the OS), unsupported rendering features, and rendering overload that causes a GPU timeout or reset. Because GPUs and drivers vary enormously, these crashes are frequently specific to certain hardware.

Quick answer: GPU crashes come from rendering problems: out of video memory, shaders the GPU can't run, driver bugs, device-lost events, or rendering that overloads the GPU. They're often device or driver-specific.

GPU crashes, where the graphics subsystem fails, can be especially baffling because they depend on the player's specific GPU and driver. They have identifiable causes in how your game renders. Here's what causes GPU crashes.

The Causes of GPU Crashes

GPU crashes happen in the rendering pipeline, and they cluster around a few causes, many tied to the diversity of GPU hardware and drivers.

Running out of video memory (VRAM), too many or too large textures and buffers for the GPU's memory
Shaders the GPU can't compile or run correctly, a shader that works on one GPU fails on another
Driver bugs, defects in specific graphics drivers that crash under certain operations
Device-lost or device-removed events, the GPU resetting or becoming unavailable (from a driver timeout, a long operation, or the OS)
Unsupported features, using a rendering feature a GPU doesn't support
Rendering overload, work that exceeds what the GPU can handle, causing a timeout or reset

Because GPUs and drivers vary enormously, GPU crashes are frequently specific to certain hardware, your code hits a GPU difference that triggers the crash.

Why GPU Crashes Are Hard to Reproduce

A GPU crash specific to a certain GPU or driver won't happen on your machine if you have different hardware. This makes GPU crashes notoriously hard to reproduce, you can't trigger them without the affected GPU and driver, so normal debugging fails.

Bugnet captures crashes tagged by device and GPU from real players, so GPU crashes surface with the hardware context even though you can't reproduce them. Knowing which GPUs crash is the key clue, since it points at a driver or feature issue specific to that hardware.

Finding and Fixing GPU Crashes

Capturing GPU crashes with hardware context lets you find the pattern, all on one GPU family, all on a certain driver, which points at the cause. Then you can address it: reduce VRAM use, fix or guard problematic shaders, provide fallbacks for unsupported features, or handle device-lost events gracefully.

Bugnet groups crashes and shows the GPU breakdown, so a GPU-specific crash stands out as a cluster. So GPU crashes come from VRAM limits, problematic shaders, driver bugs, device-lost events, and unsupported features, and finding the cause means capturing crashes by GPU to reveal which hardware fails and why.

GPU crashes come from VRAM limits, problematic shaders, driver bugs, device-lost events, and unsupported features. They're often GPU-specific and hard to reproduce, so capture crashes by GPU to find the pattern.
