Just installed Windows 7 (64bit) on my iMac because Sony Vegas was lagging on XP on my PC. Same problem on my iMac. Using Sony Vegas 11 (32 bit).

3.06 GHz processor
4GB ram

No lag whatsoever on normal clips, but when I crossfade* clips I get like 1 FPS in the preview when it's fading, and when it's over it returns to 30+ FPS?! Obviously it's not lagging in the render.

I've tried various things. Any ideas?

Video editing needs alot of RAM.

how much RAM is left while using it?

[ColorHost-Kevin]

Most likely it is your PC, not anything to do with the program.

As nobert said its about the RAM i thinks.

Lol try to reinstall, does not happen to me. I also tried my weak computer ( laptop ) no lag. So try to reinstall, also buy the legit version

I have 4GB. 1GB is being used while it's playing that part. It's not my RAM.

Change the quality of the preview.

[DuelZ]

Change the preview quality to AUTO.

I have tried EVERY preview mode. Even Draft (Quarter) - no difference.
