RTX 2070 Super doesn't show PerfCap Reason

Greetings,

As the title says, the gpu-z perfcap reason function doesn't work with my 2070s, as you can see in the image it shows "idle" all the time.
Rarely works, it's random, sometime shows it correctly i guess, mixing blue, green and yellow, or just one or two colors.

It works flawless but i need to disable hardware acceleration on web browser because my three monitors have different refresh rates and media (Youtube, Twitch...) sttuters on the second/third monitor, idk if this matters.
Performance on games is correct.


It's an MSI GeForce RTX 2070 Super Gaming X Trio, the rest of my components are:
  • i7 8700k
  • RAM Kingston 16GB (8x2) DDR4 3200Mhz
  • Motherboard MSI Z370 Gaming Pro Carbon
  • PSU Corsair RM850
  • SSD 64GB SanDisk / 500GB Samsung 840 EVO

Im a bit worried about it...
Added screenshot in idle while gaming, screenshot of the same game session both times showing PerfCap and not, and GPU info.

What's the power limit? Advanced tab

Go to "NVIDIA BIOS", which has the limits in watt instead of %

This looks completely normal now. The grey background is a valid state "not throttled, because no limit is hit"

Thanks for ur answers, but its the same game, same place etc... I mean, my old GTX 1070 showed all the time blue and green if the game was demanding, and hardware acceleration worked great.

Im being paranoid and did a MSI Afterburner check, here's my readings... Are normal these spikes?
Some games are microstuttering... I think the card is defective :(

It looks like the game hasn't high enough power consumption for your card to hit its TDP limit. The MSI limit is quite high

Thank u W1zzard.
I "fixed" my performance issues, they were due to mi multimonitor setup (144hz x 60hz x 60hz), plugged 2x 60hz to iGPU and stuttering is gone, some cards has issues with these extrange setups.

By the way, i have another problem now... Being idle my PerfCap is showing spikes of Pwr, what happens now? :(
I used GPU Shark and there's not software in background using the GPU...
