Hello,

I have some serious problems with gaming performance of RTX 3090 Ti Gigabyte Gaming and 12900K. First of all, I provide my computer specs :
 
12900K with NZXT KRAKEN X73 ( 50-60C in game )

2x16GB DDR4 KINGSTON DDR4 3600MHZ in GEAR 1

RTX 3090 Ti Gigabyte Gaming

Aorus Z690 Elite DDR4 bios F5

SSD 1 TB NVM PCIE
 
Seasonic 1300W Prime Platinum
 
 
Problem description : While testing WD:Legion performance of installed GPU, I noticed that its usage is abnormally low. In fact, I am unable to reach a “healthy” 99% GPU usage. I thought that it was due to bad optimization.
Let’s evaluate the hardware behavior in this game. Let’s assume that in location “X” .I have 120 FPS at 1080p on Ultra preset with DLSS “OFF” and RT "OFF". The GPU usage stays around ~80%. That’s a terrible disappointment. I up resolution to 1440P and still have the same 120 FPS, but with GPU usage of 90%.
Setting DLSS to “Performance” - the GPU usage drops down to 60-70% and the FPS remains at 120fps.
 
Msi Afterburner reporting cpu 30-33% usage.
 
After seeing multiple YouTube videos recorded on same hardware with usage at constant 99% - I became concerned about the situation.
For sure, V-sync and Frame Limiters were disabled. I revealed that the only way to experience full GPU usage (99%) is to max out RT to ULTRA and turn off DLSS, and run the game in native resolution 1440P.
 
Thats the issue. Now the positive sides. My scores in 3dmark ( port royal , timespy,speedway,cpu profile timespy ) are accurate for 12900K and 3090 ti. ( normal usage ). In Cyberpunk 2077,Quake 2 rtx,Control have good 95-100% usage.
 
 
Can someone explain me issue with WD:Legion?
 
 
PS:
I reinstalled windows 11 22H2 ,updated msi afterburner, tried 3 versions of drivers,still no go. Other programs are closed in background. Nothing more using cpu.

12900K,rtx 3090 . Look at usage. 1280x720 resolution. 95% usage and higher fps. I have 70-80% usage on the same settings and 30 fps less. Why?
 
 
yeah ok. But why i have the same fps on 1080P like on 1440P? Gpu usage is only different.

9900k vs 12900k would be my guess.

That sounds logical to me. 

Is your 12900k also at 5.3 GHz?

That could be the reason. The video shows the persons 12900k running at 5.3GHz.

Someone said:"

The Watch Dogs Legion seems to be working fine for me with 12900K, DDR5 6600MT/s CL32-39-39-28 and RTX 4090 at 1440p on Ultra, RT OFF with average 141 FPS, GPU usage at around 91%

Tested on second system with 12700K, DDR4 3600MT/s CL16-16-16-32 (dual rank) and RTX 3090 (Overcloked so it will reach 3090 Ti performance) average FPS at 1440p 113 FPS, GPU Usage at 99%. At 1080p average FPS 127, GPU usage at 88%.

All tests done on Windows 11 22H2 with 522.25 driver and in game (not in-game benchmark)

The game is working fine and scales just fine. It might be that you RAM isn't fast enough, Did you tune timings manually as this can increase performance by 10-20%, my DDR5 setup is tune to possible max stable and that gives a massive FPS boost in CPU limited games."





So maybe its my ram?

ok thx

I have been finding it to run worse than Cyberpunk 2077 for me. It plays fine but not the best optimized game I guess

I tested Cyberpunk 2077. Listen.
 
Using 1440P,ULTRA RT,DLSS QUALITY,rest Ultra. So switching between DLSS modes giving me more or less fps. Normal.
When i go to 1080P i have more fps than 1440P.Normal.
But when i am switching between DLSS Quality,balance,or performance i have the same fps on 1080P. I am cpu limited?
Just switching between DLSS modes on 1080P not improves my fps ,only on 1080P.

But when i turn ON RT on 1080P switching bewtween DLSS gives me more fps.
Just switching between DLSS ON-OFF or DLSS modes on 1080P not improves my fps without RT ,only on 1080P.
 
 
So 12900k is weak?

You’re running a 3090ti and 12900k at 1080p and trying to use DLSS? Did I understand that correctly?

Just for test and cpu bound,yes. Normally using 1440P.

So dont worry about that cb2077?

Ok last question. I am somewhere bottlenecked in Watch Dogs Legion?
When i go to 1080P from 1440P in benchmark i have lower 80% usage. And the same fps like on 1440P. Its with DXR OFF and DLSS OFF.

ok thx today i am formatting disk and clean installing win 11 from pendrive, i will se if that helped. But thx for all for helping.
