Does disabling dlss reduce the load on the cpu?
Currently, my only problem with this game is the CPU temp.
I can easily reach 60 fps even without dlss. Since it's useless for me, does disabiling it could help me? My GPU temp is fine.

Strictly speaking without any graphical variables; By using DLSS, you're putting more stress to the CPU if both components can maintain the high framerate. You may be referring to FG, where frame generation (DLSS3) may alleviate the CPU usage in certain situations since every other frame is generated through ML, but it's not applicable in this game. Standard DLSS upscaling lowers the internal rendering resolution, which means more work to the CPU to process more frames that will be ultimately rendered by the GPU. Both works in tandem here.

The best solution is to simply cap the framerate, creating an artificial limit to both the CPU and GPU. However in your case it may not do much if you're already capped at 60 even without DLSS. DLSS itself doesn't really increase CPU usage, only the effect of a higher framerate does. So if you are already capped at 60 then your CPU is already processing at that 60, so nothing will change other than you just decreasing the GPU usage by enabling DLSS, or increasing the GPU usage by disabling DLSS. Only when that framerate increases will you notice an increase in CPU usage. You need to look into other possibilities to lower it if you want to maintain a 60 fps target.

No. DLSS enabled is supposed to lower the burden on the CPU.

What cpu do you have? I have an AMD ryzen and have eco mode activated in bios and it reduced the max temps from 95c to 75c at the cost of 10% of multicore performance but single core difference is almost non existent and would rather run it at much lower temps and less spinning fans.

Here is an article for 7000 series but I think you can do that for the last few cpu gens.

Not sure about Intel but I imagine they'd have a similar tool. Hmm I see Intel's equivalent to Ryzen Master is XTU... these tools are made for overclocking but you can go the opposite direction and get better temps and energy usage. :)

The author of this thread has indicated that this post answers the original topic.

Thank you so much!

Cap the frame rate in the Nvdia control panel, not just in the game.
