So The Witcher 3 is out to melt gpu's away and I'm noticing the effects of FPS on GPU usage and would like people help explain how this stuff works and what people recommend. I have a i7 2600k and a GTX 970. CPU none factor. The Witcher 3 maxed out Ultra with a couple wasteful settings turned down. GPU usage is steadily maxed at 99% FPS is steadily running at 60 FPS, Temps around 70-80. If I flip the FPS to 30 GPU usage drops to 50%, temps under 70. So thoughts opinions etc. etc. etc. Can a GPU steadily work at 99% at 60 FPS with 70-80 temps for years on end or is should I drop it down to 30 with cool temps. I would assume lower temps would equally a longer life span. Which I very much want a long life span. Naturally when I see 70-80 temps and 99% usage I begin to sweat, but everyone online seems perfectly happy with these high end cards sweating away at 60 FPS.

Most people buy them to do what they do and do it well, if its capable it does it.

Some people hate 30fps, i came from 12 fps gaming to 120+, 60 i can deal but 30? never again. its a whole world of experience.

If your temps comcern you can always try adding case fans to improve airflow, or use a tool like afterburner to make custom fan profiles, by default my card wouldnt flat out its fans till 85 degrees. You'll probably find yours is only spinning fans at 70% capacity. that 30% can help drop your temps a bit.

You could set up a new thermal profile on the GPU to keep it below 70 as well without increasing the fan noise. Though a combination might produce the best results.

GPUs get warm, and those numbers are certainly better then some of the previous generation GPUs. My old 8800GTS would idle at 80C...

I've got a great case and great air flow, I've seen other benchmarks online and my temps are perfectly normal. Is temp all that matters? If the temp is good then is it fine to run a gpu at 99% for 6 hours straight? Also why does FPS double the demand? Because the gpu is doing it's job twice the amount? Going from 30 fps to 60 fps? Anyway call me crazy I can't tell the the difference from 30 to 60 when I spin my character in circles so I'm going to use 30 FPS as I don't see an enhancement from 30-60. My fans are actually spinning at 40% lol. I set them their for personal preference.
