Thanks for the reply. I have an NVidia GEForce 9400 GT, using the latest proprietary (closed source) driver for Fedora 16. I've verified that the driver matches the kernel: Code: kernel-PAE-3.2.5-3.fc16.i686 kmod-nvidia-3.2.5-3.fc16.i686.PAE-290.10-1.fc16.13.i686 xorg-x11-drv-nvidia-libs-290.10-1.fc16.i686 xorg-x11-drv-nvidia-290.10-1.fc16.i686 I tried running glxinfo and get: Code: OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce 9400 GT/PCI/SSE2 OpenGL version string: 3.3.0 NVIDIA 290.10 So I think the NVidia driver is installed correctly. How can I test Direct3D in Wine? If I try running dxdiag.exe in Wine, it never opens and I get: Code: fixme:win:EnumDisplayDevicesW ((null),0,0x32d6e4,0x00000000), stub! fixme:win:EnumDisplayDevicesW ((null),0,0x32d604,0x00000000), stub! fixme:ddraw:ddraw7_Initialize Ignoring guid {aeb2cdd4-6e41-43ea-941c-8361cc760781}. fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {33d9a760-90c8-11d0-bd43-00a0c911ce86} not found fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {33d9a761-90c8-11d0-bd43-00a0c911ce86} not found fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {cc7bfb41-f175-11d1-a392-00e0291f3959} not found fixme:devenum:DEVENUM_ICreateDevEnum_CreateClassEnumerator Category {cc7bfb46-f175-11d1-a392-00e0291f3959} not found fixme:dxdiag:wWinMain Information dialog is not implemented I'm not if dxdiag.exe should work in Wine anyway. Please let me know, and Thanks!
