      Some drivers will recompile shaders under specific conditions, for instance when a uniform value becomes 0 or 1, in order to eliminate noop expressions (e.g. add 0), eliminate conditionals, reduce register pressure and total instruction count.

      Nvidia used to be very aggressive with such optimizations back in the geforce 5 and 6 days, much to the annoyance of game developers. Typical workarounds include small epsilons (e.g. 0.001 or 0.999) or multiple side-by-side shaders that are bound depending on uniform combos.

      As gpus got more complex, these optimizations became less prevalent, but it could very well be that some drivers might still use them.

        Wow, I was about to write the very same thing o______O
        Except it's been two years since Phoronix is on my AdBlock black list.

            no. they work on steam for linux for over 2 years .

            they just do have performance problems because of the "bad" linux drivers.

              Oh, Gaben sent you a mail too.
              Right.

                not "gaben" it was a person talking about gaben.

                  Let's assume this is correct.
                  Aren't the Mac OS X OpenGL drivers far worse?

                    this is not the point the point is: they want support ALL linux drivers.

                    and the status of "ALL" Linux drivers are..... sad...
                    also its about how to benchmark drivers if you benchmark with outdated games like quake3 then the result is always invalid.
                    i know Phoronix always benchmark in this way.
                    also 2 years ago they also hold back the linux steam version because of macosx problems.

                    now they are finish the macosX work they now do have resources for linux.

                    also there was a contract between apple and valve apple pay for the steam clind and the openGL support and the contract between valve and apple was that apple comes first.

                    this means they are only allowed to do a linux clind after the macos clind is perfect.

                      allquixotic: ok I could believe the cases where a shader is being optimized/changed at runtime, which would require a recompile. I find it hard to believe though that memory consumption would be a reason. Shaders are small so I think you would need 100's or 1000's for it to be an issue.
                      Really vertex and texture data should be the main consumers of the vram.

                      Qaridarium: for some reason your confusing vertex data with a shader.

                        The OS X drivers are far worse as far as comparing them against the Nvidia binary on Linux, and maybe even fglrx under certain circumstances. But the OS X drivers are a lot better than the open drivers most of the time.

                        Remember, we're talking about the Source engine. It's pretty much going to be limited to using OpenGL 2.1 anyway. All the content in Source engine games is assuming that the user has DirectX 9.0c (OpenGL 2.1) class hardware, nothing newer. So any support for GL3+ is irrelevant in the comparison.

                          also the steam clind for linux is not for "Profit" its about PR and the good reputation

                          the people don't understand why linux is always doomed because of this they blame valve for not support linux.

                          even the macos and windows customers blame valve for not support linux.

                            Do the headers suggest the mail originated from valves office? Would love for this to be true, but I can't help but think the mail will turn out to be fake.

                                I get tired of April Fools. Every year. Again. Over and Over. And Over. It's one day of the year where old dumb jokes which weren't funny the first time find their way back and there is no damn way you are going to avoid them without unplugging your Internet connection. I think I may try that soon.
