Hi, I have a PC with two graphic cards one Intel onboard and one Nvidia dedicated card. lspci shows me both and both graphics drivers are installed. Code: > lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9300M GS] (rev a1) wine.log shows me: Code: trace:wgl:wglGetProcAddress func: 'glAccum' trace:wgl:X11DRV_WineGL_InitOpenglInfo GL version : 2.1 Mesa 7.10.2. trace:wgl:X11DRV_WineGL_InitOpenglInfo GL renderer : Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20100330 DEVELOPMENT x86/MMX/SSE2. trace:wgl:X11DRV_WineGL_InitOpenglInfo GLX version : 1.4. trace:wgl:X11DRV_WineGL_InitOpenglInfo Server GLX version : 1.4. trace:wgl:X11DRV_WineGL_InitOpenglInfo Server GLX vendor: : SGI. trace:wgl:X11DRV_WineGL_InitOpenglInfo Client GLX version : 1.4. trace:wgl:X11DRV_WineGL_InitOpenglInfo Client GLX vendor: : Mesa Project and SGI. trace:wgl:X11DRV_WineGL_InitOpenglInfo Direct rendering enabled: True trace:wgl:has_opengl GLX is up and running error_base = 170 I think, Wine only uses the slow Intel card. Is it possible to force Wine to use the NV card instead and how?
