Description Gregor Münch 2017-03-05 19:35:03 UTC
Created attachment 130078 [details] menu options With higher GL versions, Dirt enables "advanced lighting" options in the graphics menu. Setting this to "On" makes the game basically a slide show. FPS is going down from 60 to 10. Im on a Radeon HD 7970. Also all other Radeon cards seems to have a performance problem: http://www.phoronix.com/scan.php?page=article&item=mesa171-pro60-rx470&num=2 where figures looked better in 2015 (but probably because Opengl 4.5 wasnt there) http://www.phoronix.com/scan.php?page=article&item=dirt-showdown-linux&num=3 Some more infos about the lightning options: http://www.rage3d.com/articles/gaming/codemaster_dirt_showdown_tech_review/index.php?p=2

Assigning to the radeonsi driver until we know it's a general problem...

(In reply to Kenneth Graunke from comment #1) > Assigning to the radeonsi driver until we know it's a general problem... FYI Kenneth, I have access to a binary of this so could collect some data on where time is getting spent, I just need to download the thing..

Still a thing with current git.

Created attachment 137129 [details] Ingame Looks like this is one of the last games which have pretty garbled graphics with mesa. What is needed to fix this?

I recorded a trace but I think its useless because of: https://github.com/apitrace/apitrace/issues/232 Is there anything what could be done here? From googling around I saw Marek got a trace working maybe you could help here?

The low performance is a known issue. We don't know if it's expected or not.
Comment 8 Gregor Münch 2018-03-27 13:34:54 UTC
All graphic options are set to the maximum possible value including MSAA. Its not only about low performance, once advanced lightning is set, the graphic is also seriously bugged, including wrong textures.

Found YouTube video on Nvidia showing same settings, including advanced lightning working flawless and good speed. https://youtu.be/hP4V5W-IRJ0?t=4m49s However in a phoronix article, Michael is showing ingame pictures showing cars with obviously missing textures. (Yet he claims that the game is looking good and the same for both vendors) it's the same kind of corruption I see with activated advanced lightning btw. Though I additionally see over bright lights. https://www.phoronix.com/scan.php?page=article&item=dirt-showdown-linux&num=4 The performance with catalyst was still way better than Mesa.

Created attachment 138979 [details] ingame benchmark mode The cars with texture errors seem to be either a game bug or Phoronix Test Suite bug. If you select the Benchmark mode while you in the actual game, the cars are rendered correctly. However the graphics are still broken. Seems to be a problem how the lights got applied to the objects.
