i wanted to report an issue i’ve been able to reproduce consistently in both vegas 22 and vegas 23 on an RTX 5080. enabling dynamic ram preview appears to cause a runaway gpu memory leak that eventually destabilizes the entire system.

what happens:

with dynamic ram preview set to 10%:

• during playback, dedicated gpu memory usage continuously climbs higher and higher. it only stops climbing when i pause playback.
• even after pausing, the gpu memory doesn’t release. it just sits there until i disable dynamic ram preview entirely.
• if i let playback continue without pausing, eventually my entire system fails (audio drivers, other applications, everything).

with dynamic ram preview disabled (0%):

• playback is stable, with gpu memory sitting in a safe range (8–9.5gb).

Dynamic RAM Preview turned ON:

Dynamic RAM Preview turned OFF:

this isn’t just performance degradation.. it’s kind of a critical stability issue. a runaway memory leak that consumes all available vram until the machine fails makes dynamic ram preview unusable in vegas 22/23 for me, at least.

so! the open question, i guess - is since this behavior shows up for me in both vegas 22 and 23, i’m trying to determine:

• is this a vegas issue introduced in 22 onward that affects all or some gpus?
• or is this specific to how vegas interacts with the new 50-series architecture?

can the dev team (or anyone else knowledgable) confirm if this is a known issue? if not, could it be investigated? this feels like a serious regression, and i suspect other users may be hitting the same problem without realizing dynamic ram preview is the trigger. I'm really interested to know if this is 50 series specific.

happy to provide videos, logs, or further testing if that would help. My specs are in my signature.
