NVIDIA RTX Virtual Workstation - Video Editing Performance Not Usable

I stood up a test workstation in AWS (detail below) to test video editing and collaboration.

I connected via RDP. The specs prior to launch displayed 1GB of GPU memory in AWS console, but upon opening the servers’ Task Manager, the GPU apparently has 15GB of GPU memory.

I installed Blackmagic Design DaVinci Resolve, my editing software, and uploaded a short, unedited video to test.

Without making any modifications to the clip, playback of the video was very choppy. Do you have any ideas or suggestions?
