I have recently built a new PC aimed at video editing. It has a Ryzen 3700x cpu, 1660super gpu (graphics card), 16gigs of ddr4 ram, and a Samsung 970 pro m.2 ssd. When I first started editing with this computer, I realized that my pc only used cpu and ram to create the playbacks and render my videos, so I tried to use my gpu through the Mercury Playback Engine GPU Acceleration(CUDA). With this, my GPU began to prove its value, until the render stops randomly in the middle of processing, and Premiere crashes. I have checked to make sure this is a gpu isolated problem by rendering with the Software only setting, and it works perfectly (but very slowly). I have also tried to only use the graphics card for playback, since it didn't work for rendering, but the screen goes black in the playback monitor and I am forced to quit and restart Premiere. I have done all of the driver installation from nVidia (both the normal drivers and CUDA drivers), and I have tried the troubleshooting tips from other conversations in message boards, but it seems that my problem is a unique one. I am starting to wonder if it is really a gpu problem, or its because I am misunderstanding the usage of gpus in video editing. Please send help, I have spent way too much money on my rig to just throw away the use of my graphics card. Thank You.
I would like to add that the option to turn on the Acceleration through CUDA is avaliable (like I can choose to turn it on) but it leads to the problems I have listed above (renders freezing, black screening, crashing), and I have tried the clean reinstallation of drivers. I would also like to add that the CUDA acceleration being turned on does give me the benefits of acceleration and my GPU is fully utilized when the acceleration does work (near 100% utilization in task manager), but I have yet to get a complete render out of my system using that method (again due to the problems listed above). Premiere Pro also doesn't give me any error codes, it just freezes or crashes. I have attached a screenshot of my attempt. The GPU is under full load when the render works, but after awhile the render freezes and my gpu is no longer being used (this can be seen by the huge spike in performance, then the huge drop).
Premiere doesn't use the GPU every second for many processes, it uses it for when there are GPU accelerated effects involved in a sequence (and for those bits) as the CPU gets to the part where the GPU accelerated effects are. They have added some use of the GPU for H.264 encoding, but if I recall that may currently need an Intel CPU still. I could easily be wrong on that, and I hope that RJL pops in as he knows this stuff cold.
So ... set your GPU use to Mercury Acceleration/Cuda in the Project settings dialog. And that's all you as a user can do.
Now ... the latest Nvidia drivers are wonky. Go back to either the 445.x or 442.x drivers, from the Nvidia site, and use their options to do a clean install of the Studio driver.
Thank you for your reply Neil! I will try what you have said, and will respond with the outcome.
I have tried installing the 442.x drivers and it does the same thing, renders for a little bit, then the render freezes (same problem as mentioned above). Anything else I can try? I'm somewhat frustrated, especially because if CUDA acceleration doesn't work then my graphics card is stuck twiddling its thumbs. Maybe thats what I don't understand? When I use CUDA acceleration, it looks like my cpu shares its load with the gpu somewhat, and the render seems faster (while it works). When CUDA is disabled, all of the load is put on my CPU and RAM (usually 100% load) and my gpu does nothing. Granted, when I render with CPU and RAM it does render, but it is both painfully slow and slower than the CUDA accelerated render. Its frustrating because CUDA works for a little while then it stops all render processes, so I can see the potential of GPU acceleration, but it has never rendered successfully.
I'm having this issues too. Sometimes it renders sometimes it gets stuck around 18% - 25%

Update to the latest Nvidia Studio drivers. The game-ready drivers have been causing all sorts of pain.
I experienced it too img! it pains my work please can someone told me how to fix this
