FPS drops, GPU in use higher than total GPU?

Hi,

Could someone explain to me how my gpu_mem_used can be higher than total_gpu_mem?

I’m having drops in fps.
Normally I get 50-60 with my current system and now I’m getting 30 or lower.
Can’t seem to really figure out where this is coming from.
I’ve used the probe and cookbar tool.
When checking the performance window, ‘Presenting windows’ sometimes takes about 50ms.

Thanks in advance!

It can be higher because the OS/Driver is able to move some data out to the CPU memory. This is similar to the pagefile.sys which is HDD/SDD space used to hold CPU memory content.

When this happens though, things can get very slow. So the first step to improving your performance will be to reduce your memory usage.

Thanks for the clear reply!
I’ll continue my search.
