Summary: GeForce FX: Extremely low performance with NPOT textures Product: Wine Version: 1.2-rc3 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d AssignedTo: wine-bugs@winehq.org ReportedBy: fao.wine@gmail.com
The quirk used to prevent the use of OpenGL 2.0's NPOT texture functionality on GeForce FX-series GPUs is not applied to all cards in that series, leading to software fallback on them.
Adding a check for CARD_NVIDIA_GEFORCEFX_5200 to dlls/wined3d/directx.c:match_geforce5() corrects the issue completely.
For reference, my specific card is the FX 5500 with driver version 169.12.
