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

[Bikerdude]

[update]

Hi bikerdude

 

As I understand it, most of the issues have been resolved in the driver that is expected to be released shortly.

 

Amd

 

[update]
The Darkmod Issue is still being worked on. While the issue has been reproduced and identified, the solution is pretty complex and is taking longer than initially estimated. I’ve not been given a firm date for the fix but it should be in Q1 2015.

-----------------------------------------------------------------------------

As some of you may be aware I have trying to get to the bottom of the OpenGL perf issue that AMD/ATI card owners have with our mod (based on IDtech4), as in the game becomes slow and laggy with fps drops. The aformentioned perf drops would happen where either the Draw Call count hits 1500 (Doom3 vanilla max) or there are too many particles or overlapping lights in a scene etc. see thread -

- http://forums.thedar...n-atiamd-cards/

The more people that report this issue, the quicker we will be able to have a fix made available to us. Im in contact with AMD atm and once I have said driver update, I will post a copy of the driver for people to test and give feed back here.

So what would be helpfull is for anyone that has a HD5000 series or higher card to: Load up the training mission> go the archery range> and then while standing in front of the table near the entrance look down the range. Then post in this thread with the same details as below please.

Cool.

 

Nice work.

The aformentioned perf drops would happen where either the Draw Call count hits 1500 (Doom3 vanilla max)....

 

Where is it located in the code?

Why not to increase draw calls limit?

[nbohr1more]

That's nowhere near the drawcall limit. He's found that performance is tanking on ATI hardware where the drawcall value is extremely low

and a much lower spec-ed Nvidia chip outperforms his brand new card.

[motorsep]

Btw, try using older drivers. Sometimes old drivers do wonders. That could be of help to AMD team and help pinpointing where they made a mess.

Exactly, the issue is with the driver which is what is being looked at by AMD.

 

So what would be helpfull anyone that has a HD5000 series or higher card to load read the OP and post the requested details.

[SteveL]

I'll follow those instructions when I get home Thursday. I'm not sure I can make an independent report to amd. The reason your report was so persuasive is that you were able to compare their card against an older nvidia under controlled conditions. Not something most of us can do!

[Bikerdude]

Makes no difference, and on an R9-290 there is only so far back you can go. If you dont have an ATi/AMD please reply in one of the other threads, ta.

Crossfire HD5770 (not sure if crossfire is enabled in TDM)

[Lux]

Crossfire presents other issues in and of itself as I'm sure you're aware.

 

If you run the game in windowed mode it should only use your primary card by itself though that may present separate issues from full-screen mode.

@Lux, do you have an ATi/AMD card..? if so can you post as per the OP..?

Additionally i made an interesting observation: my minimum fps in that area were 19 and when i turned off aa the minfps changed to 14, which absolutely makes no sense to me.

Added the above posts to the OP.

[HMart]

Update on the frames for second, decide to update my drivers to the new 14.9, gained minimum 4 fps and was even able to reach 38 fps's sometimes, with or without crossfire.

Unfortunately not. Running a 780gtx :\ and have been running Nvidia since GF3Ti500.

[kyyrma]

Here you go:

• FPS: 39
  
• System: Radeon R9 280, Intel Core i5-3750k 3.40Ghz, 8gb DDR3-1666, Asrock H61M-HVS, Windows 7 Home Premium

Also thanks for looking into this.

[motorsep]

Btw, Doom 3 engine (and TDM engine likewise) is CPU bound, optimized for Intel. So the higher resolution and the lower CPU clock (especially for AMD CPUs), the lower fps will be. It seems like it doesn't have much to do with GPU.

 

AAx8 and anisotropic filtering murder performance in Doom 3 too.

• It seems like it doesn't have much to do with GPU.
  
• anisotropic filtering murder performance in Doom 3 too.
  

• Ive clearly demonstrated it IS to do with the GPU or its driver.
  
• AS has next to no perf downside unless your using a very low end GPU.

Thanks from me too Biker!!

Maybe I missed the whole Nvidia vs AMD comparison thread, sorry. Do you have the comparison stats between Nvidia and AMD on otherwise the same PC ?

[Bikerdude]

Do you have the comparison stats between Nvidia and AMD on otherwise the same PC ?

Look at my other threads in the Tech support section mister.

[motorsep]

• Fps ~34 (with "preferred maximum performance")
  
• System -- Nvidia GeForce 670 GTX 2Gb, AMD Penom x3 2.2Ghz, 8Gb DDR, xfx 750a, Sound: Asus Xonar D1, Win 7 Pro 64bit
  
• Driver -- Nvidia's latest release
  
• Screen res -- 1920x1200
  
• Settings -- AAx8 ASx8, VSync off
  

Note, Nvidia. As I said, it's not all AMD. It's also engine being CPU bound.

Go into the nvidia control panel and check the "power management mode" and set it to 'preferred maximum performance', if it was adaptive you'll get a massice increase in FPS. Some gpu/driver combinations mean that TDM isnt detected correctly, for example on my GTX970 with the 344.11 driver, with PMM set to adaptive the driver was correctly detecting TDM was running and my FPS was half what it should have been etc.nVidia have since fixed that in the latest driver 344.48.

Did that, edited my entry. Still, fps is no better than for AMD folks.
