[Gtx 980 In 2Way Sli Not Being Utilized.]

You need to use high voltage to get it stable. For 4GHz i need to set the voltage to 1.47 V.

[Gtx 980 In 2Way Sli Not Being Utilized.]

with SLI disabled it runs about 70%

 

with it enabled both run at like 25%

 

the biggest issue this causes is that i have to keep switching between enabled and disabled when i switch games. which is stupid as hell.

hmm, looks like warframe really prefer nvidia GPUs, because even if i overclock my 1090T CPU to 4 GHz i don't get that high GPU usage.

[Gtx 980 In 2Way Sli Not Being Utilized.]

What is your gpu usage with sli disabled? I have same cpu but with R9 290 and my gpu usage is really low, like 30% max.

Same here. I noticed that on dx9 all cores are used for shorter time than in dx11. So i use dx9

[Multi-Threaded Not Working Properly?]

Warframe started as singlethreaded game. Multithreaded rendering was added only later, which offload some work to other cores. That means that one core will utilized all the time and others when its needed. To properly utilize all the cores evenly, game engine must be developed as multithreaded from the start (Frostbite 3)

That being said, your card shouldn't do that badly. Are your drivers up-to-date? And do you have the any driver overrides in the AMD control centre? AMD usually have very bad drivers for Nvidia supported games.

 

I don't use control center at all, It isn't even running in processes. Drivers are, lets say up to date. For last couple of months amd only releases almost identical beta drivers (I use 14.7 RC1 and latest are 17.7 RC3, but they are almost identical.)

 

I was using DX11 until 14.5 warframe update. After that on DX11 my FPS dips to 30 in some cases and I don't find it acceptable, therefore I play on DX9 which gave me minimum of 150 FPS.

[Fps Difference Between Dx11 And Dx9]

Using Vsync under DX11 mode, but not under DX9?  On my shuttle's bridge I see about 260 FPS on DX9 and 240 FPS on DX11, with Vsync off.  With Vysnc on, both are 58-60.

 

Vsync is off on both. (I cant stand the added lag with vsync).

All settings are identical. I double checked it even, to be sure.

Something must be hurting FPS on DX11, on my system.

[Fps Difference Between Dx11 And Dx9]

Why is there such huge FPS difference between these two?

On DX11 I'm getting 63 FPS.  http://oi58.tinypic.com/2e4hvg5.jpg

On DX9 229 FPS. http://oi58.tinypic.com/qzkeq9.jpg

 

I have enabled multithreaded rendering.

On both DX11 and DX9 I can see only one core fully utilized but on DX9, GPU usage is higher also FPS is significantly better.

 

My PC: AMD x6 3.6 GHz, 8 GB ram, AMD R9 290

[De What Is Up With The Performance ? (U 14.5)]

Try changing to DX10 in launcher.

On DX11 I was getting 45 FPS on average, with DX10 I'm getting 150FPS on average.

 

Edit:

DX10 mode wasn't running properly, so game would run in DX9.

So try game in DX9, it gives game FPS boost.

[Better (And Needed) Video Optimization.]

....

please, move the visual processing entirely to the GPU. it's where it belongs. we could even move Physics there.

 

Cannot agree more, when I play my GPU is resting while I'm having low FPS because CPU is hammered with all the work.

[Optional Multi-Threading: Feedback.]

I can see the same problem on my 6 core cpu. I was playing warframe with osd, showing me utilization of each core and I can clearly see that most of the time only one core was fully utilized. Strange thing is that every once in awhile all cores was utilized around 60%. I presume that this is not bug, but poor multi-core optimization.
