Flat frametime and no stuttering at all playing Cyberpunk at 4K

Ive managed to get stable FPS but more important stable frametime and 1% lows almost as high as average FPS.
FPS: 90
Avg FPS: 90
1%Low: 80
Frame time is FLAT at 11.1 ms.
GPU Usage is at 99% so it seems that is running as it should.

Pc Specs.
CPU: 7600x / GPU: 4070 Super / 32GB DDR5

I got my PC like a month ago.
And was having really unstable gameplay on Cyberpunk.
1% lows were a joke.
And the framtime graph had a lot of spikes.

My CPU runs very hot (7600x runs closer to 95C)
So i had to do several things to make this work.

Steps.

Undervolt your GPU:
Stock: 1.1v at 2805Mhz
Undervolt: .960 at 2730MHz no change to power limits.
I actually get better results on TimeSpy at the lower voltage and frequency stays always at 2730.

Cap your frames on Riva Tuner:
I was getting around 80-110 FPS (really unstable) and my frametime was horrendous.
I capped at 90FPS (and it worked great).
Only downside is that CPU load increases a lot and so does CPU temperature.
Without capping the frames i was playing at around 70-75C / 80C max.
After capping i was playing at 80 hitting highs at almost 90C. (I tried several games and it seemed that only Cyberpunk increased the CPU temperature, other games reduced CPU temperatures.
So i had to do an extra step.

Undervolt your CPU:
I tried a lot of different configurations and finally got one that is as stable as it gets.
Even better that without undervolting.

Best undervolt that i have tested.

Curve optimizer: -12 on all cores.
TDP: 97watts.
Thermal throttle: 95C

On Cinebench without undervolt CPU was hitting 96-97C.
With undervolt i had a max temp of 78C.
So it almost reduced 20C temperature.
20% lees heat for the CPU

I am really enjoying my gameplay.
If anyone has any questions i would love to help!
