OpenGL perf. on AMD/ATi gpu's: WIP fix.

[motorsep]

So anyhow, I wonder what now?

[nbohr1more]

Yeah, we really need to fix the timedemo feature and release a new benchmark. Then, hopefully, phrononix (etc) will use it and it'll put

pressure on AMD to improve their benchmark results. As long as there's no press about it, this will always be a low priority issue for them.

[motorsep]

I doubt Phoronix has any weight in this matter. He has been bashing AMD for ages, and nothing has changed on the OpenGL front.

[nbohr1more]

Yep, we'd wanna convince tomshardware, anandtech, kitguru, hardocp, or hothardware to add this to their suite.

guru3d too.

So, any news on this issue?

 

I would imagine AMD engineers should really be able to pinpoint the issue knowing that 13.1 works and current driver doesn't.

[Bikerdude]

Will chase tomoz.

New drivers out.....same performance in TDM

[motorsep]

Same in a sense as "poor as it used it be" ?

A little bit worse.

[motorsep]

A little bit worse.

 

Ouch :/

 

@Bikerdude: Do you think you can explain to AMD about 13.1 atioglxx.dll performance boost ? (if you can tell them about BFG engine, maybe it will give them better clues, since TDM doesn't have break down on timing for various subsystems)

[lowenz]

No, I'm joking, it's really the same.

 

Ah, try to rename to "Wolf2MP" and you'll have MORE optimization than "DarkAthena"

 

GCN+Catalyst performance is really tied to profiling.....

Why not to try Brink, Wolfenstein 2009 MP, Quake 4 MP and see if any of those have even better optimizations ? (since all of those id Tech 4 based)

Im hoping they will have created a new profile for us.

Wolf2MP is the MP exe of Wolfenstein 2009

[motorsep]

Wolf2MP is the MP exe of Wolfenstein 2009

 

Oh, cos on YouTube videos Wolf2MP looks like WolfET

 

How much is performance better with that one ?

 

What about Brink profile or Quake 4 MP (seems like Quake 4 MP would be closer to id Tech 4 than anything else)?

[lowenz]

TDM standard:

Wolf2MP:

Brink:

Doom3: FREEZE @FM loading screen

[motorsep]

Seems like Wolf2MP is the best bet right now. No Quake 4 MP profile ?

[Bikerdude]

Has anyone tested the new 15.4 driver..?

I'm testing, see before and this one below

 

Quake4MP.exe result:

 

And the winner is Wolf2MP profile

[motorsep]

Fun fact - renaming our engine to Wolf2MP.exe yields 1 fps in the menu o.O

 

Rage.exe boosts fps a bit.

 

That's Doom 3 BFG based, not Doom 3 based engine.

They changed something in the new driver package (15.5).....now TDM performs differently in some areas.

Differently how? Better? Worse? Same'ish ?

[lowenz]

In some areas worse (or maybe I miss something but my system and TDM have the same old settings.....and I deleted the AMD shader cache):

 

15.4 Wolf2MP

 

 

15.5 Wolf2MP (29-30 FPS vs 40)

Correct screnshot (With FPS OSD). And obviously the V-Sync is OFF.
