I have just built a pc on budget with the following: vista x64 gigabyte ga-p35-ds3l Mboard q6600 @2.4ghz cpu xigmatek s1283 cpu cooler w/crossbow & as5 paste ati radeon hd3870 gpu 8gb corsair ddr2 6400 800mhz ram 320gb WD HDD corsair VX450w psu antec 300 case etc... In autocad I am fairly happy with the rendering times but it is still very slow to work with when 3d modelling (in wireframe) and switching views. (swivelling the view with a 3d orbit is totally out of the question) My drawings are built up with alot of 3d models. e.g. a social club with a bar, windows curtains, carpets, light fittings and also full of furniture. I know with my cpu cooler there is room for overclocking the cpu but i will probably only go to 3.0ghz as stability is crucial. (this will help my rendering but not my 'realtime' modelling in viewports) The files i am opening (40mb) take 5-10 minutes to open. could my problem be to do with my graphics card? I know that a workstation card such as the firegl would have been better but they are very expensive. I have read about softmodding the 3850/3870 to firegl drivers/capabilities. Apparently this is only working in xp x32 & x64 at the moment. Would this be worth a go, if i ran xp x64 instead of vista x64?
you can try dual booting xp64 with the softmodded HD3870 and vista64, but xp64 barely has support. there's nothing more you can do, other than fork over the cash for a firegl or quadro. the hefty price tag is there because it's used in businesses.
what do you mean? xp64 barely has support? I wouldn't mind running solely on xp64 if it makes life easier..
my hd3870 is now running as a firegl v7700 on xp 64bit, but its still shockingly slow. I'm wandering wether it has something to do with the software or drawing, as i think my spec should be able to cope with what i'm asking from it. If i try to import the drawing into 3dsmax it also takes ages to open, but can actually be rotated when opened. (although i'm not familiar to 3dsmax)
...it was more of a software thing than anything, because the file was so big i was able to uncheck some options in the display to optimize performance. Its perfect now, and 3dsmax is even smoother.
