Vietcong crash #42

Open sonicpp opened 5 years ago

sonicpp commented 5 years ago

Vietcong (AppDB) video game is using D3D8, but community tool called VCStarter converts D3D8 calls to D3D9, so it is usable with Gallium Nine (this tool is not applicable on demo versions, unfortunately).

This game runs quite well with Gallium Nine, except it crashes in certain situations, like when player is looking at handmap. Also fire is not rendered at all. Very similar issue was (almost the same I would say) was in WineD3D (bug #46849), but Gallium Nine is suffering by this issues even on Wine versions which are not affected by this bug (like Wine 4.9 or Wine <= 4.1). Note that there were similar bugs in WineD3D before, like #46359 and #46403.

The bug seems to revolve around ProcessVertices. Wine and nine support different features of ProcessVertices. It's highly likely we don't support the d3d8 parts, while wine does, which explains the lack of fire. While the crash could be solved quickly I hope, ProcessVertices is harder, in particular because the lack of test cases. Could you take a trace under wined3d ? https://github.com/iXit/wine-nine-standalone/wiki/apitrace

Here is the trace: https://drive.google.com/open?id=17GaVVlCuXUYNSzPyzdi6Pctmbq5DUYw4

The fire around helicopter is not visible with GalliumNine. Also when I switch weapon to handmap, the game crashes with GalliumNine.

@orbea had some success with https://github.com/crosire/d3d8to9, maybe that works better?

Looks interesting, thanks for info. VCStarter does more than just coverting D3D8 to D3D9 tho. It fixes also some crash places. Although I know how to fix them (see appdb for details), I have to manually patch Wine-staging to get it work. Not a lot of work, but I need time and mood for it :)
