--- Comment #6 from Kai kai@dev.carbon-project.org --- Ok, I did one last test. I only set "MESA_GLSL_VERSION_OVERRIDE=430" (notice the missing override for MESA_GL_VERSION_OVERRIDE in comparison to comment #0). When launched this way, TressFX works (at least in the benchmark, I used to check this and to produce the trace from comment #5)!
I'm closing this bug as NOTOURBUG as it seems the game is using functionality, when the TressFX option is enabled, it should only use when GLSL 4.30 is available. Or put differently: it shouldn't offer TressFX unless GLSL 4.30 is available, ie. this is a game bug.
The launcher problem described in comment #0 seems to stem from the fact, that MESA_GL_VERSION_OVERRIDE also overrides the compatibility profile version as well and the launcher then uses that instead of a core profile. While forcing GLSL to 4.30 only enables 4.3 in the core profile.
