Hello Adobe community. I've read through several threads regarding rendering slowness, but swear this is different! 🙂 I have a new computer build that is a monster, and I have run benchmark tests and all are within the acceptable range. I rendered a 15 minute 4K video with the same configuration as I use on an older machine but it's taking 2x to 3x as long, e.g. it's taking over 60 minutes to render. On my older build, Premiere Pro uses the GPU, but on this new build it does not.

Computer build

Motherboard: ROG Strix X570-E Gaming AMD4 Architecture
CPU: Ryzen 9 5950x
GPU: XFX Speedster MERC319 AMD Radeon RX 6700 XT
Memory: G.SKILL TridentZ RGB Series 4 x 16GB 288-Pin DDR4 SDRAM
Storage: 2 x WD_BLACK 2TB SN850 SSD (Gen4 PCIe, M.2 2280); one is used for read, and the other for OS and writes
OS: Windows 10

Notes

Motherboard and GPU drivers are up-to-date
Reading 4K .mp4 from drive M: and writing to drive C:
When rendering, I see barely any disk activity, and barely (if any) GPU activity; however, CPU usage is around 50%
The Renderer: under Video Rendering and Playback in Project Settings is set to Mercury Playback Engine GPU Acceleration (OpenCL)
During benchmark tests, GPU shows activity.

Any feedback would be greatly appreciated! If you need more information about the setup / configuration, please let me know and I will provide.

Thanks!

Have you considered using a CODEC that supports Premiere Pro Smart Rendering?

If you're creating content for YouTube or social media, I would go with Apple ProRes422 LT.

If you're creating content for broadcast or cable, I would go with Apple ProRes422 HQ.

I render to H.264 for social media. I don't have any issues and Nvenc and Quick Sync can export the H.264 real quick. The H.264 video codec will create a small file that will be just fine for achiving.

You ever figure this out? I have nearly identical specs with the exception of a 3080 and it is extremely, painfully slow with even the simplest of video editing.

When you go to Preferences > Media, are the options for H264/H265 hardware accelerated decoding and H264/H265 hardware accelerated encoding available? If so, are they enabled?

H264/HEVC hardware accelerated decoding / encoding are both enabled. Thanks for responding!

Did your old system have Nvenc or Quick Sync? There is a difference between GPU acceleration and GPU encoding and decoding. The video below might be helpful.
