GPU Performance not what it should be??

[ItsSquishy123]

Hello,

 

So I have a RTX 4070 laptop (ROG Zephyrus 16 2023) and I found that whenever I do any GPU intensive task like playing games or doing 3D CAD in solidworks or Fusion 360, it seems remarkably slower than what I was expected. In games, the fps is only have of what it should be. For example, in CS2, I only get about 70fps on average when I should be getting like 250fps. I have tried everything: installing the newest driver, running DDU, clean up all my files, disabled all startup program, ensuring that only the dedicated GPU is being used and the laptop is being plug into the walls.

 

I have scoured the internet for a solution but I couldn't found anything. The only thing I have done to this laptop is bought a 16GB stick of RAM to make it 32GB in total. The only thing abnormal I could find is the fact that my VRAM usage is very high in games. For example, when I open up CS2, the VRAM usage jumps up to 85% while my GPU usage percentage is around 30% and my temperature is at around 60.

 

If anyone have any ideas, It would be greatly appreciated.

Thanks

where are you getting the fps you should get? laptops gpus aren't as powerful as the desktop versions.

Just videos on youtube. Yeah I know that it isn't as powerful but there is just no way it is that low in CS2. I played on like medium - high and it only gets like 70-80. The videos I saw all got like 150-200 at least.

what cpu do you have in the laptop and what is its utilization when playing? are you sure the 150-200 fps weren't on low settings?

are you definitely using the full spec PSU?

 

laptops will grind on battery and crawl on USB power, even 140W USB-C will restrict the CPU/GPU if there isn't enough power as it needs to ration it out... CS2 is normally CPU bottlenecked, so make sure the CPU is boosting enough to feed the GPU the frames that you want it to draw.

 

the picture you've shown is just a GPU that isn't being used much; top-down guess, this implies the CPU isn't feeding the GPU.

 

what is the CPU spec and is it boosting properly...

I agree... However, laptop GPUs came a long way (since a while I guess?)

My 4070 *mobile* is on average slightly slower than my desktop 3070, but not by that much (not bad) and actually pretty much what I expected, and on top of that it outperforms the 3070 in some newer titles due to the fact it has much better framegen (yeah it's fake frames but still smoother than potentially sub 60fps on the 3070 - monster hunter wild says hello, even though since I turned off volumetric fog it runs around 70-80 fps so similar to what I get with the 4070)

Laptop is running in a low TDP mode

 

and/or

 

CPU is being the bottleneck or busy running background apps

Good call - I was going for somebody accidentally throttling the power via incorrect PSU or insufficient power delivery: I know I see a HUGE difference on my laptop between battery, 140W USB-C and the proper ~250W brick.

Agreed - if the power delivery is fine, it might be BIOS low TDP mode or Windows power settings... or some manufacturers throttle their CPU/GPU power due to overall power/thermal budgets in a particular chassis, but at least check that the CPU is able to boost to the expected levels.

I'd check Windows Power settings first: I had a problem where my DESKTOP kept dropping into efficiency mode in the Windows settings and throttling the CPU to 800Mhz: same symptoms - GPU RAM was being used (same image on the screen), but utilisation was very low as the CPU simply wasn't feeding it enough frames... 60fps max, rather than 200+...
 

Should be quick to check.
