Issue

testfit error stating: "Your graphics system is not supported by TestFit. This is often due to out-of-state graphics card drivers. Please contact out support team for assistance."

Cause

Out-of-date drivers are the most common reason for this dialog to appear.

Solution

Make sure your graphics card (GPU) drivers are fully updated. These can usually be installed from Windows Update or your hardware manufacturer's website.

If the dialog persists after updating your drivers, then Windows may be attempting to run TestFit on an integrated graphics card, which are less powerful and may be unsupported.

If you have a dedicated graphics card, you can tell Windows to use that instead by using the following steps:

Go to Settings > System > Display. Scroll down and click the “Graphics Settings” link.

Under Desktop apps, choose testfit.exe in the C:\Program Files\BuildingForge\testfit\ directory. Set it to use the High-performance GPU.
