Hi Mitch,I'm certainly not disputing what you say you get in terms of performance. I guessed that PAI must have considerably less flights than UT or MT. Less Ai = higher frame rates. Maybe I should lower my 100% setting but I have great difficulty removing things I have paid for :-lolSo why does the 1.5 rule for the page file stop at 4Gb??? Answers on a postcard to Bill at Redmond! :-lolThanks for including your system spec in your sig :-)

Hi Rhett,<>Okay, I don't want to get into a protracted debate but some suggestions were a little vague about an actual size. No matter. I understand enough about the page file to know it needs to accommodate the entire contents of RAM.<>Only if there is sufficient space on the drive. Unfortunately I have several unmovable files on mine which prevent one contiguous file. The only way to create a single file is to format and reinstall the OS and all apps but that isn't about to happen.<>No, FS is now too large for the Raptor and resides on the Maxtor 200Gb.<<...I suspect Windows XP is also making a small paging file on your C: drive whether you like it or not.>>Only if it's invisible :-) I removed the existing one, rebooted, deleted the pagefile, defragged and then created a new one (4Gb). No sign of a second one :-)Cheers,
