If “Fatal error” pops up now and then when you start the game or log in, and the game closes, the problem is almost always on the graphics card side. Netmarble gives 3 fixes; try them in order and launch the game once after each.
1. Clean-install your graphics driver
Grab the latest driver for your card from NVIDIA or AMD. Netmarble’s tip: uninstall the old driver first. If the error is still there after installing, restart your PC and launch the game again.
If VAMPIR shows “Fatal error” on PC, first uninstall your graphics driver and install the latest one. Still crashing? Turn off hardware-accelerated GPU scheduling in Windows, and if you have both integrated and dedicated graphics, disable the integrated card in Device Manager.
2. Turn off hardware-accelerated GPU scheduling
First finish any pending updates in Settings > Windows Update. Then go to System > Display > Graphics > Advanced graphics settings, switch Hardware-accelerated GPU scheduling off and restart your PC. This path is for Windows 11.

3. Disable integrated graphics if you have two cards
If your PC has both the CPU’s integrated graphics and a dedicated card, the two can clash. Open Control Panel > Hardware and Sound > Device Manager, expand Display adapters, right-click the integrated card and pick Disable device. The screen flickers once, and that means it’s applied.
Is my graphics card good enough for VAMPIR?
| Brand | Minimum | Recommended |
|---|---|---|
| NVIDIA | GeForce GTX 1060 | GeForce RTX 2060 |
| AMD | Radeon RX 580 | Radeon RX 5700 XT |
| Intel | Arc A580 | Arc A750 |
If your card is below the minimum, a new driver may not fix this error.
