The Hi-Rez textures are around 2500x2500. I'm starting to think it's a cpu temperature problem along with a memory seeting not being right in the OS. I need to allocate more memory for Poser. After I got off my computer this afternoon (it was on for about 7 straight hours) I rested it for about three hours and then as soon as I turned it on I opened up Poser immediately and tried to open one of those problem files and IT LOADED PROPERLY. About 20 minutes later it started acting up again after I shut poser off and re started it. The files would not load again. So I know nothing is wrong with the files...something is happening after the computer either warms up or something else is happening with system resources or memory. I checked my bio's and the CPU temperature was at 149 degrees. I think this is a bit high, don't you think? Yes the old 233mhz was a Pentium cpu. This new 1400mhz is an Athalon cpu.
