3800x here and it's the same. In balance power mode the CPU idles at 1.4 volts average and temps are like 45 degrees on average. Cooler is Noctua DH-15. It's like the CPU just doesn't want to go really idle. Switching to power saving mode fixes it though. Voltages in power saving are like 0.9 and temps 35 while idle.

Ok so i disabled the SMT and it seems like there is an improvement. The CPU usage seemed to jump up a bit as well. I wouldn't say the issue is gone but GPU usage got better in those particular games. I'm surprised that 3800x could be a bottleneck for a GPU. I never did it before so i need to ask. Would you advice leaving SMT disabled for good?

Thank you. I was just playing with kingdom come and i noticead that changing the draw distance does affect the GPU usage. Although the cpu runs comfortably at 30% in all cases. But CPU bottleneck doesn't explain to me why the GPU starts running at 100% if i push the resolution up beyond the native resolution and it doesn't affect the framerate. If CPU would be bottlenecking the GPU then GPU shouldn't be capable running at 100% under any circumstance right?

I just tested two other games PUBG and Resident Evil 2. Both on steam and both were running perfectly without any issues. The GPU utilization was 99% on the native resolution and everything was working fine. So it seems like in some games the GPU refuses to run at full speed on native resolution and would rather lower it's usage then lower the framerate when the resolution is droped down. And slowly increase it's usage when the resolution is pushed beyond the native resolution untill it hit's the full load and it finaly starts doing what it should and start dropping framerate if pushed even further. But it isn't every game apparently.

Just ran it for you and everything seems to be working properly. The final score is 22376. Graphics score 26092, Physics 24057 and combined 10279. GPU doesn't have a problem to run fully in any benchmark. The issue seems to occure only in games. Also the CPU is nowhere near or running on 100% in any game i mentioned. And as i said the GPU is capable to run on 100% stably. Either when i push that resolution scale or in that safe mode of Metro exodus.

I have a weird problem i never experienced. It seems my 5700 Xt doesn't want to run on 100%. But the problem is more complicated then that. Because i found out that the GPU usage is somehow tied to the resolution in a weird way. Without vsync or freesync enabled whenever i change the resolution instead of framerate it actually changes the GPU usage. For example i tested Kingdom come deliverence. Maxed out in 2560x1080 resolution on the certain spot i have 53 fps and GPU usage is very unstable from 60 to 85. When i lower the resolution to 640x480 the framerate stay exactly the same but the GPU usage falls to 40% or so... In WoW i can test it the other way around because it has a resolution scale up to 200% of the resolution you use. So when i set the resolution to 2560x1080 again the GPU usage jumps around 60 to 85 unstably. But when i start increasing the resolution scale up to 150% i can actualy see the GPU usage to increas and get more stable untill it reaches 99% and stays there. After i push it beyond the 150 i finaly start seing the fps to drop down and it works fine. So the card is capable to run stably under a full load. It just doesn't want to or refuses to... Last example Metro exodus on Xbox (beta). This game usualy just crashes on start up when i try to use it with MSI afterburner. But when i manage to run it after a few tries it is the same. GPU usage jumps around 70 +/- 15. But whenever that game crashes the windows offers me to run it in ''safe mode'' next time and whatever that safe mode does it fixes the issue. GPU usage is stable 98-99%. Naturaly it has a big framerate boost compared to runing it out of that safe mode and it just works as it should. If anyone actually knows what causes all of this i would be very grateful and thanks for reading through all of this wall of text..
