Bug ID: 52625 Summary: Vertex texture fetch advertised on R300-R500 class AMD hardware Product: Wine Version: 7.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d Assignee: wine-bugs@winehq.org Reporter: pavel.ondracka@gmail.com CC: stefan@codeweavers.com Distribution: ---
I'm not 100% sure if this is an app bug, or if wine messes something up, but Unigine sanctuary reports:
Found optional Vertex texture fetch
and later fails badly, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/6053
This is with mesa r300 driver (latest git). None of the R300-R500 cards have vertex texture support and as far as I can see mesa correctly reports GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS = 0
BTW Anno1404 under nine also produces TXL opcodes in vertex shaders, but there is might be also gallium-nine problem. The Sanctuary is with pure Wine.
