AMD Radeon RX 5700 endless 100% GPU usage while preview

pavel.lu wrote on 4/1/2020, 3:46 PM

Hello, I have a new installation of Vegas 17 pro 421 on a machine with AMD Radeon RX 5700 8GB (driver 20.3.1). When I enable the hardware acceleration in the setup (Preferences>GPU acceleration of video processing > Optimal - Advanced Micro Devices Inc, gfx1100) I can't generate any preview. When I click on any video with Vegas Video Stabilization FX, the GPU has 100% load and the program is unresponsive in a while. The only way is to kill it in the task manager. I have tried to wait for 10 minutes, but it didn't help. If I turn off the acceleration, everything works fine.

1. Update your graphics drivers.

2. Worst case, you can disable GPU Acceleration of Video Processing. This will slow down your preview, but won't affect rendering.

Thank you, I have the latest driver. The second option works, but I would prefer to have the acceleration on, if it's just a bit possible.

I have changed the card for GeForce RTX 2060 and everything is fine now.

For others following this thread... Others have reported that some of the newer AMD cards, like the RX 5700, etc. have some driver issues affecting Vegas stablity & performance... However, IMO, these are overpriced mid-range cards. AMD has not released their latest high-end cards. Therefore, IMO, for the money you are better-off with an earlier generation of discounted high-end cards, like the AMD VEGA 56 or 64 which outperform both the RX 5700 & RTX 2060 in VEGAS... In order from fastest to slowest in my workstations... My refurbished liquid cooled $350 VEGA 64 is fastest, then my used $200 air cooled VEGA 56, then the RTX 2060 in my laptop, and lastly, a RX 570.

Czy Vega 64 jest lepszy od RX 5700 XT?

TheRhino wrote on 4/14/2020, 5:27 PM

Although based on newer, smaller, and cooler technology, the mid-range RX 5700 & XT only have 36 / 40 nCU compute units, the VEGA has 56 & 64 respectively, and the Radeon 7 has 60... (The Nvidia 2060 has 41). The older VEGAs use more power, but only when pushing them... My liquid-cooled VEGA 64 performs more like a Radeon 7 because it can be undervolted & clocked higher due to the excellent cooling...

They have a Vegas 17 page too, but it was based on an earlier V17 release that crippled the performance of AMD GPUs...
