Well, I have 4 GB's of RAM, and I actually don't see lag.
Or maybe I'm so used to lag that I don't see it. (5 year old PC + TF2 = less than 26 FPS)
Though I have a 64 bit windows and I would like to try it out.
But the problem would be how much memory should I dedicate to unity?
How many FPS do you get in game? And with which settings?
If you have 4GB give Firefox about 3GB or 3.5GB, it won't go that high tho.
Edited:
Going to give it a try,I hope this works!
Thanks!
EDIT:Ddidn't nootice any diff,am I doing it wrong?
Go to http://unity3d.com/webplayer and check your unity web player version
Make sure that when you start Nightly, firefox is closed, otherwise it'll open another firefox window.
How many FPS are you getting in game? And check memory that plugin-container is using on task manager
Edited:
Me neither. FF64 and UnityWebPlayer64 and grass.on off.
Helped a bit but not that much.
Use Fraps or any program and check if your FPS is capping at some point, like 50 or 60.
