    wine skyrim dont work in fglrx for me and never did(4850x2, 7770, 7850, r9-280), even latest beta crash the game.

    My mods include
    Several parallax improvements mods
    SMIM
    TrueVision ENB
    hell lot of 4k and uncompressed texture mods including fairskin or true daugthers of skyrim mod uncompressed
    LOD improvement mods
    SKSE latest(including eshon memory stuff)
    lots of parallax 4k landscape mods (verdand, treebark, sfo, etc), btw my grass is at 40
    water and climate mods(SLO, tw2, etc.)
    high resolution replacer mods for face, armors, weapons, eyes, mouth, brows, animals, hair(sg+apachi+combined sg)
    high density meshes for CBBE bodies + spms32 skeletons with extra bones for stuff...
    every hot mama follower ever created
    lots of skse dependant mods like EFF, and others for stuff ....
    falkreath <-- Awesome
    Including all settings set in ultra + custom decals and LOD
    this ofc include ENB Antialiasing which truevision set it very high(not sure if SMAA tho)

    With this settings depending the fglrx version, i've been able to trigger even kernel panics, where radeonsi with gallium nine runs it at playable framerate for hours (better than windows 7 sometimes since i guess wine handle better 32bits memory limit per processes and avoid kill the apllication when it reach retard amounts of RAM (falkreath is a killer in windows sometimes, too much rocks with 4k uncompressed textures to fit in 2GB ram)<-- i guess, havent go that deep to be sure).

    same applies to CIV5 for me, vanilla civ5 runs fine on fglrx but when you start modding shit hit the fan, with radeonsi i just loose FPS(due graphical mods ofc).

    with skyline fglrx works ok but i get nerve wrecking stutter randomly or just Puff crashes(with 7770, 7850, r9-280 aka ll GCN class hardware maybe with r600 is a different story) when i stop playing for few mins(going to bath for example), with radeonsi it 100% stable and smooth all the time

    Note im not saying fglrx just doesn't work(it was like that before tho) and i admit there has been improvements but i judge drivers for more than simply come to phoronix and see which one has the bigger FPS bar, for me versatility, stability and features matter a lot. I mean if one driver let me play 60+FPS but crash when i mod for me is useless and i will prefer always the one that let me do whatever the hell i want without fail but show 35 FPS in those pretty phoronix bars and i mean everytime hands down but if your thing is FPS then that is your choice and that is fine

    IF ubersampling is only using the GPU, then my system is not CPU-bottlenecked.
    Cause if I switch ubersampling on my FPS goes down from roughly 25 to 12 (measured with gallium hud)
    This was last measured on radeonSI, mesa 10.4.3, llvm3.5, kernel 3.18.3 (opensuse Tumbleweed), see:


    (I will update my data at github when llvm 3.6 hits tumbleweed)
    sorry, should have clarified- my testing was based on fglrx driver. That causes a CPU bottleneck and the GPU to be underutilized.

    With mesa, although generally slower the bottlenecks are probably different as you mentioned.

    Does it use an OpenGL backend on Windows? If not, can the game use an OpenGL backend on Windows? It would be interesting to see Windows OpenGL vs DirectX comparistions.

    I can speculate that playing witcher 2 on Linux with uber sampling on vs off may not see much performance difference. Because on Linux in graphically advanced games AMD GPUs are always heavily CPU bottlenecked even with a modern i7. I don't think turning on ubersampling will change that equation much because it asks the GPU to render at a higher res and downsample, CPU will probably remain the bottleneck.

    Driver overhead is that bad... Powerful GPUs like the R9 290 in witcher 2 are not working hard, nowhere close to 100%. It's just the driver hitting a wall and getting CPU bottlenecked. The GPU usage looks totally different when I play witcher 2 on windows. The driver doesn't get in the way and the GPU is working at 100%; higher GPU temperatures, the fans spin up and become slightly audible and of course much higher frame rates. On Linux the R9 290 never breaks a sweat, I guess it's not being supplied with draw calls fast enough so it just waits..

    well llvm 3.7 and latest mesa + 4.1-rc1 improved a lot my r9-280 lately on Arch, in fact i can play the witcher 2 on Ultra with upsampling on with RadeonSI
    nice - i have the same card and wait to play witcher 2 with ubersampling too (looks so much better)!
    What CPU do you have? I am afraid that there is my real bottleneck...
    And what fps do you get (enable gallium hud if you don?t know).

    I guess you can't really compare a 6970 with a R9-280, can you? Also, which "version" of the open drivers did you try? The open stack is in constant flux and thus, using the very latest versions can make things a lot better!

    completly false, in fact most linux steam games and UT4 linux build run better on FOSS drivers than fglrx(probably this will hold true once metro redux is supported in FOSS drivers), fglrx specially suck ass in team fortress, cities skyline, X3, the Witcher 2(is unplayable), Civilization 5 with certain mods(dunno which since i have 60 active mods and im lazy to find out which of those are allergic to fglrx since radeonsi works just peachy). Aditionally wine and fglrx is a big HELL NO to play my windows steam games like Skyrim(+158 mods), deadpool, grid, etc

    R9-280 OC sapphire
    AMD fx6100@4gz
    16GB DDR3 2100
    ArchLinux + lcarlier mesa git
