MSI GTX 970 GPU Usage fluctuates causing stuttering

[aquilaray]

Hello, I am experiencing a very irritating problem and need help with it.

When playing the witcher 3 I'm have continous fps drops (like it's stuttering) it's really annoying.

I went to investigate what could cause and then found the fps drops occur when the gpu usage drops.

My GPU usage is then like this: http://prntscr.com/d5hzvq

Anything I could do?

Thanks in advance!

There's your problem. You're at max VRam usage. The last 0.5 GB of VRAM might as well not exist, and you're running into VRAM issues. Basically the GTX 970 has segmented VRAM. The first 3.5 GB is fine and normal, but the last 0.5 GB, due to disabled architecture to keep the price down, can only be accessed at about the same speed as regular system memory. This was a scandal with the card because you get stuttering and performance drops once you hit 3.5GB VRAM usage despite the box saying 4GB. Hell, NVidia didn't even disclose the disabled ROPs and Cache in the original release so no one knew until they ran into the issue you're having.

You need to play with lower quality textures
