BioShock Infinite Can Run More Than 23% Faster With New RadeonSI Patches

You need the new DAL modesetting code for HDMI/DP audio support. It's not upstream yet, but you can grab it here:

https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-4.6

Nice thanks! This is only kernel 4.6 no? If I just pop the latest /drm/amd/dal files into the 4.7 source and compile that, will that be sufficient? or should would it be better to just grab everything in /drm/amd*, or perhaps also /drivers/amdgpu?

Thanks! But that's only 4.6 no? Can I just grab the 4.7 source and copy in the /drm/amd/dal code? or should I grab all /drm/amd*? (or possibly also /drivers/amdgpu?) Or am I better off just compiling that whole tree?

11 FPS is too low. Just in case, what is the output of the following commands while playing Bioshock?

cat /sys/class/drm/card?/device/pp_dpm_*clk
cat /proc/cpuinfo | grep MHz

not on my pc right now, but card clocks were 13xx core and 2000 mem, cpu iz i5 3750k at 4ghz, all clocks forced.

So, don't jump on him immediately... OK, maybe after 5 posts

Thanks, also i have arch, tried kernels 4.7/4.8, llvm is 4.0. But yes, I do come from mint - before buying rx480 never needed any more custom distros and knowledge

Deleted, duplicate post

OK here are more details.

Bioshock Infinite - Ultra settings - Full HD:

Radeon 285 (weaker than 480) on AMDGPU:
- before: 20 FPS
- after: 25 FPS

Radeon 290X (more CUs but lower clocks than 480) on RADEON:
- before: 18-20 FPS (I don't remember exactly)
- after: 26 FPS

Is there still some other bottleneck stopping the cards reaching their performance potential? Shouldn't the 290x be about 35-40% faster than the 285 based on the GPU hardware?

Is there a benchmark mode in Bio:inf ? Seem to have a vast difference in perf compared to them

I was playing this earlier as Mageia 6 has kernel 4.7 with CIK support enabled.

Using mesa 12.1 with AMDGPU @ 1440p all maxed out lowest has been mid 50's(looking across water) up to 130+ on a 290x
Do get the odd stutter.

Tried Borderlands 2 too , 100 + most of the time also at 1440p

Been quite impressed with it so far, Ballistic overkill has issues with it though.

Think I will have to put PTS in, though It never seems to like me


Edit:

To add, this is on a 4790k

The stutter might me shaders compiling. Eon stores them in a .dat file and compiles on first occurence afaik

Never thought of that, It does give the impression that its loading something occasionally so it could well be that streaming in so to speak

Will this help TeraScale hardware too?

A person who patches mesa uses llvm 4.0 and is not a beginner like you are.
