Question

How much VRAM do I need to run CUDA efficiently?

I'm using the GTX 1060 3GB and somewhat struggling with both playback and rendering. Premiere would crash randomly when I apply LUTs, rendering would stop at the heaviest FX timecode and return an encoding failure. Until I turn off GPU acceleration completely. It takes a little more time but gets the job done everytime. I'm currently on CC 2018. Is it just my card or the CUDA has been this GPU consumptive all the time?

    What media are you using? That would have an immense effect here. If it's 4k drone/mirror-less/DSLR media, H.264 ... that's long-GOP and is a right punker on the CPU for playback in an NLE. The fix is actually to use the included Cineform proxy presets on ingestion, or after importing, select the media, right-click, "Proxies/Create Proxies" again using one of the Cineform presets. Do NOT use the H.264 preset ...

    For 1080 media, I would expect the 1060 would be handling things pretty decently for those things that are GPU oriented. Decoding/decompressing H.264/long-GOP for playback however is a CPU/threads/RAM task, not a GPU task.

    Do not count on Windows to be fully up to date when it comes to device drivers

    Go to the vendor site to be sure you have an updated driver for your graphic adapter

    There are also intermittent reports that the newest driver is not always the best driver due to driver bugs or compatibility issues, so you MAY need to try an earlier driver version
