Sony vegas pro using CPU


Aug 30, 2015
I've recently started using Sony vegas, and i realized that when i go to render a video, it takes an ungodly amount of time, and pushes my CPU to its limits. After doing some research i noticed that its using my CPU to render instead of my GPU. so i followed all the tutorials online that i could find to set it to you my GPU instead. But still it uses my CPU.

Things ive tried:
-Changing my render settings to use CUDA as an encode mode.
-Changing my GPU acceleration of video processing to NVIDIA

CPU: i7 4790
GPU: GeForce NTX 970
I have a similar issue. The gtx 970 will not be used since it is not supported by gpu. Rendering is very CPU heavy anyways (unless you have quadro) so it would make little difference.
