A Variety Of Unreal Engine 4 Linux Demos Are Now Available
Pay attention to the header of the window, then compare GLSL version to that of driver. We ain't fully OpenGL4.x yet.
Unreal Engine 4 use OpenGL 3.2 renderer by default.
There is OpenGL 4.x renderer, but it's have to be activated manually.
And yeah this TGSI error completely unrelated to GLSL version support, it's shader complication backend error.
Unfortunately default R600 shader compiler fail to compile many complicated shaders and LLVM backend is incomplete.
PS: This doesn't change fact that UE4 still have bugs that make it incompatible with Mesa, but this TGSI error is completely unrelated.
You mean graphics cards with "real" drivers? Like closed source nvidia-blob? Should you also buy real closed source OS? Hypocrisy much? Driver is just several years old, and already went near OpenGL4.
I hope you use an open BIOS, and open CPU microcode, and hardware schematics, and open....
Otherwise you'd be a hypocrite.
Seriously though, Linux has a pretty good claim to being the best OS, period. Similarly the nvidia driver is the best GPU driver. Therefore I use them both.
It would be nice if the nvidia driver was open source, but since there are so few people with the skills and desire to improve it, I don't think it's particularly important. The situation with radeon drivers shows that it's no panacea.
