Could be.....but I find simply using the P4 renderer to be an easier fix than messing with resource settings, changing file sizes and the like. I have a PIV, 1.7ghz with 512 mb DDR ram and XP pro. I've rendered textures a lot larger than this using the P5 renderer. It seems like their must be something in the way firefly renders the hair files.....but with P5 it's hard to say :) The link includes comments from Neftis, the hair creator.
