Upgrade GPU for previews?

[Matt Kipis]

Hi

I’m trying to increase my preview speeds as its taking so long. My pc struggles when I need try and preview clips with CC Force Motion Blur set high (shutter angle 400, Samples 15) also at 4k.

I did check task manager and I can see my GPU usage hitting 100% at times. Looks like a GPU bottle neck.

I currently have a 2070 Super 8GB so 2 generations old I was thinking of upgrading to a 4070 TI 12GB which is a pretty big jump about 137% speed boost

It is pretty pricey I was wondering if you think its worth it performance wise. If I will see a big improvement with previews with motion blur and maybe rendering too?

I heard AE with updates is getting better at utilizing the GPU so maybe a good investment in the future if they keep going down this path.

Other PC specs

RAM 128GB

AMD Ryzen 9 5900X

SSD M.2 Drives

Thank you

Also I use Warp stabilizer with every clip too

Neither CC Force Motion Blur nor the Warp Stabilizer are GPU-accelerated effects, but both are pretty heavy effects. I don’t think upgrading your GPU will give you the results you’re looking for. You’re probably better off tweaking your workflow (previewing at lower resolutions, previewing with skipped frames, temporarily turning heavy effects off, pre-rendering or proxying, etc.).

GPU-accelerated plugins/effects have a little badge next to their names (a play triangle icon with three speed lines). You can also find a table showing every built-in effect and its support for multi-frame rendering, GPU acceleration, and different color depths here:

I just dont understand why does my GPU usage hit 100 percent when i preview CC motion blur it must use it somewhat?

Im already previewing at quarter resolution, is it possible to preview lower then that?

what is pre rendering?

thank you
