Question GPU not at 100% in Cyberpunk games

Hello everyone,
I recently added an RTX5070 ti to my setup, so here's my complete configuration (I'm playing in 1440p):
Processor: AMD Ryzen 7 5800X (8 cores / 16 threads)
Graphics card: RTX 5070 Ti
RAM memory: 32 GB DDR4 (Corsair, max frequency 3200 MHz XMP)
Motherboard: MSI MPG B550 GAMING EDGE WIFI
Power supply: Corsair RM850X (850W, Gold certified)
CPU cooling: Corsair iCUE H150i ELITE CAPELLIX (Watercooling 360 mm)
Storage: SSD NVMe: Samsung 970 Evo 1Tb
NVMe SSD: Samsung 990 Pro 2Tb

I did a test on time spy and got a good score (22938) and reached 100% on GPU. But on Cyberpunk, I notice that my GPU rarely goes up to 100%, as if it were limited.
Yet the CPU doesn't reach 100% either (it's at 76%). So why can't I push my GPU harder in games? On Cyberpunk, I play in full ultra, dlss + frame gen 2 as well as ray tracing. I guess I have a CPU bottleneck, but do you think it's significant or “light” enough?

Please let me know if you need more information! Thank you and have a nice day

Your cpu is working really hard during the game. I believe your gpu is just not being utilized because it is waiting for the frames to be sent to it. If you are getting 146 fps and not suffering any stutters or lag I would just let it be. Or you could try different settings, higher or lower, and see if the gpu puts out more effort.
 
It's important to understand that the CPU will never reach 100% when gaming even if it's bottlenecked because games are not designed to fully utilize all the cores (unlike the GPU that is specifically built to be fully utilized in games).

Your 76% usage is very high and suggests your CPU is pushed to its limit but it's not really surprising: you are using DLSS, which means the game is rendered at a lower resolution, so even harder on the CPU, and ray tracing too, which is also CPU demanding (most people think it's only demanding for the GPU but it's not true, the CPU also contributes to RT calculations).

What is your monitor refresh rate? Are you using a fps cap or V-Sync (which would cap your FPS to your monitor refresh rate)?

Anyways, 146 FPS looks pretty good to me.

Thanks for your reply ! I understand better now and everything seems logical. I have a 165hz ecrn and I think I'm using G-synch, would you advise me to disable it or not? Thanks !

No keep G-sync on. I was just wondering that if you had a 144 Hz monitor and using V-Sync, you would have been capped at ~144 Hz (which is good to prevent screen tearing). I personally always use G-Sync and if the frame rate of a particular game can reach my monitor max refresh rate, I also enable V-Sync. Actually, the lowest input latency (without screen tearing) is achieved with G-Sync + V-Sync + Nvidia Reflex, according to this guy.

Edit: if you "think" you are using G-Sync, you are likely not. To make sure you are using it, first make sure your monitor's VRR is enabled (G-Sync or FreeSync) and then open the Nvidia control panel and go the G-Sync tab. There, you have to enable it in both sections (top and bottom of the page) and click on apply. Plenty of people think they are using G-Sync but they actually aren't because they haven't done all those steps.

I'll look into that when I get to the PC, thanks for the info!

I also wanted to know if it might be interesting to look at the 1% low to see if my bottleneck might or might not be “important”, what do you think? If so, how many FPS would I need to get to still have a good experience? Thanks
