OpenGL 3.3 renderer rewrite

[fudje]

Are open source drivers able to run current shader path?

No, but pretty much only because of the use of floating point textures.

There's a pretty high chance that Mesa3D won't be able to run any sufficient complex 3d game at playable frame rates. Given that 3d speed is not even a priority for the developers: "From a high-level RedHat point-of-view we aren't interesting in gaming level drivers. ..."

Neither are the AMD Linux Catalyst guys, who are effectively adapting workstation graphics drivers to run on consumer hardware. As it happens, on my (IGP) Radeon 4200, fglrx is barely faster than recent mesa3d versions when vdrift is run without shaders at this point. It's 'unplayable' on either with the shaders enabled (setting aside the shader path issues that mostly result in rendering errors). I haven't tested with nouveau, but I hear reports from some other games that it's less RAM (don't know about VRAM) intensive than the nVidia binary blob and gives higher frame rates in some situations.

My concern is only that persons with graphics cards that aren't so old and can handle sufficient shader complexity to make vdrift look like it's a new game rather than one programmed in the mid 90s, but aren't supported by any vendor-supplied closed source driver, might be being excluded. This includes anyone with an Intel IGP, and a not insignificant number of Radeon users.
