>>5239989Without knowing more about their environment I can't say this for certain, but it doesn't seem like this would be a GPU issue. Or rather, it isn't an issue of lacking GPU horsepower. There's some latency somewhere that is causing her position to not get updated in time. The scene they are rendering is NOT AT ALL complex, so I am guessing some part of the software is poorly optimized. That is: the GPU isn't stressed, but it's not being given instructions in time, for this-or-that reason. Could be any of a hundred details, and would be inappropriate to speculate further, but that is my hunch.
The last time I did anything related to this kind of work was almost a decade ago, so someone else can chime in if they think I'm wrong. I just don't see the issue being "needs better GPU".
