Catalyst 14.4 Has Advantages Over Linux 3.15 + Mesa 10.3 Git
Yep game immediately segfault when i check that option, but not when i am in start menu Of course that is workaround with Smooth LOS, but postprocessing remains black whatever or how i set it.
Spotted blackiness in Unigine Sanctuary today too, i don't know how Michel can benchmark that driver when rendering is so broken . Who cares if fps is faster when rendering is broken
well in my 7700 since llvm 3.5 this issue dont happen to me in any unigine demo anymore and yes oibaf is right if i restart the game with all options active it works just fine for me, the issue is just when you switch them in realtime, llvm 3.5 also fix some weirdness in Civ5 BnW under wine i had with old LLVM stack. Also i noticed that my 7700 dont slowdown either with 3.15 kernel + PTE patches compared to 3.14, so i guess many of this radeonsi issue apply mostly to GCN 1.1+ hardware.
in my case the only bug i seen affecting my GCN 1.0 card is you truck game trace
I overall considered radeon driver at 40-80% GL performance level of Windows Catalyst. And we are at the same level for more then 10 (fuckin' years baby yes ) years, so nothing changed for that matter in more then 10 years . I use r200 driver ~10 years (and compared it from the dri1 times when it perform the best that is around 2006. just before AMD cames with their opensource strategy), and now i see radeonsi is on the same level when compared with Windows Catalyst, so i can clearly say - absolutly nothing changed there with GL performance wise .
When i say that i always excluded bugs in radeon (there are many bugs out there), i just considered that N/A .
10 years ago, hd4830 with no DPM did 1 fps software rendering with radeon; and 300 fps in catalyst, with 40fps at pixel_vomit map with bloom+flares+hires textures.
Today hd830 with radeon has automatic DPM and it does 280 fps and 40 fps at pixel_vomit map with bloom+flares+hires textures (since kernel 3.15+Mesa 10.2.2).
Alone the fact how open radeon destroyed closed source macos, which has similar marketshare to linux, shows a LOT.
Your R100 card is over 10 years old, what improvement do you expect? Pick more modern card and do a time travel. This is considering Linux.
With windumbs, there is no point in time travel because it has HUGE marketshare. So referencing windumbs has only a point as a maximum achievable performance and not as a usable alternatives. Because in that case, thats completely wrong forum.
