Tried x5 or x4 scaling? x6 is total overkill (it's 3072x2682 if you didn't realize...). Also check if your GPU is running in 2D clocks or not, because it looks like that's happening...or your processor is throttling (check the second using cpu-z)

When you get the slowdowns, use a monitoring tool like GPU-Z and see the clocks your graphics card is running at and if they are matching your graphics card maximum ones.

research your graphics card maximum speed and compare it to the one "GPU core clock"
if it matches it means your GPU is maxing out and is your bottleneck

Yes apparently my guess was correct, your graphics card stays on 2D usage clocks. Try some other nvidia driver maybe or setting the windows power plan to performance
