I have seen this several times already. IMO the reason is that 3D game developers often have much better hardware than (casual) players, thus skewing their perception of requirements upwards. It's a losing battle to try to convince people with gaming GPUs that not everyone has them, and a few years after games drop the renderers that make games go fast on older and weaker hardware, affected users stop playing those games. > If Mesa's Vivante driver is providing misleading version information and > the driver actually has better functionality than what it advertises, > that would be something to take up with the driver's developers (but > bear in mind that this is a reverse-engineered driver for a 10+ year old > GPU design, so don't expect miracles). > > smcv I have asked in #etnaviv on the OFTC IRC network and austriancoder gave me the following explanation for underreporting driver OpenGL versions: > there are reason why we do not expose higher opengl versions - some > required features like 128 bit formats are not supported by the gpus > and need to be emulated. a fancy feature from a higher opengl version > works per se, but the spec requires support for 128 bit > formats. that's why you might see a perf boost. To me this seems similar to the situation in which the Mesa drivers for older Intel integrated GPUs intentionally report to support only OpenGL 1.x instead of 2.x; because otherwise applications (like Chrome) choose a rendering path that uses newer OpenGL, but is slower on the hardware. Given that evidently darkplaces works with the GPU in my MNT Reform 2 (and possibly other GPUs that report lower OpenGL version numbers for similar reasons), I wonder though if setting the environment variable could be added to a launch wrapper … would that create other issues? The worst I would assume is a crash or seeing a very slow main menu. I vaguely remember that there used to be some configuration to adjust graphics options for specific applications … I do not recall details.
