Does GPU matter most for dense cloud layers?

Recommended Posts

I've heard there clouds in particular stress the GPU, but tell me more of what you know. If I am at the same resolution (1920x1200) and go from a GTX280 to the latest nV card or a 570, will this mean more dense clouds will have less of a negative impact on frame rate? If so, by how much? I'm on an old Penryn quad, however the question is for a total system upgrade, so would be going w/ an i7-2700 or i7-3770 . . . or Haswell ;o) Right now very dense clouds in ASX really do stress performance. I have clouds in FSX set at max miles and density.

not sure, but I just flew a flight through thunderstorms and my GTX580 3GB was at 95% gpu utilization, although I'm not sure for how long. With a slower GPU it would surely have been saturated and the performance would have been affected. Never used more than 700MB of RAM.
