Depends on your VRAM and if it's getting throttled or not.

Are you using Windows? If so the Task Manager has a Performance tab where you can see what's going on.

Depending on your settings and the resolution of the gen, genning takes up a certain amount of VRAM. If you're doing other things that take up VRAM and your GPU doesn't have enough for both, something will get throttled.
