I've finished it, uploading to FTP. It took a while to connect to your FTP, about five min but uploading now at 30kb/s 50 mins remaining.
Great job by all, some very nice skins. I didn't have to do much, Shark you forgot to resize normal .tex files to half of ultra size. Folloiwing the original GTR car files for resolution size and DXT format you can't go wrong. Minton, yours I don't think would have worked but it should do now.. I sent you PM but that explanation I gave earlier somewhere else I can't find it atm but it describes everything quite well.
Btw i've not got my GFX card, could have got it today but then found out I need an adaptor to PSU. So will be running by Monday hopefully.. this means i'm not able to check it. I'm confident it will work but there may be some issues. If you could do 52 grid race at Spa Shark, one race with Hi-rez and one with Hi-rez disabled just to make sure it doesn't crash or anything, maybe quick scan through some skins that would be great. Have fun with test on Sunday, see you at Brno nGT sprint with new car pack if all goes well.
