There is a video of the same effects on youtube ( <a href="https://www.youtube.com/watch?v=n35hwmN3VmQ">https://www.youtube.com/watch?v=n35hwmN3VmQ</a> ) that was made shortly after the release. Also the developers said multiple times it'd need OpenGL 4.3 and especially compute shaders - check <a href="show_bug.cgi?id=93144#c8">Comment #8</a> or the posts by Feral employees on the steam forum (for example post 32 from [FERAL] Edwin here: <a href="http://steamcommunity.com/app/214490/discussions/0/490123938446209677/#p3">http://steamcommunity.com/app/214490/discussions/0/490123938446209677/#p3</a> ). I don't think it's a bug if the game wants 4.3 and we only got 4.1, and I trust the devs if they say it needs compute shaders. Of course it's a bit strange that it looked better on i965 before they had compute shaders, according to Tapani Pälli in <a href="show_bug.cgi?id=93144#c12">Comment #12</a>. @Nicolai Hähnle, <a href="show_bug.cgi?id=93144#c10">Comment #10</a>: well, it fires up a dialog that the graphics driver isn't supported and asks you if you want to continue anyway. I think I didn't get that dialog when I forced mesa to 4.3 (it doesn't help). I actually think it's not a bad idea to let the user decide. To add some not-yet-mentioned info: the effect you see depends on the setting for SSAO (Screen Space Ambient Occlusion). If you set it to "Off" or "Standard" you'll get the flickery colours everywhere. If you set it to "HDAO" it's way less flickery (fog still does), but way too dark. Maybe that's a hint why radeonsi is different compared to i965 ?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
