Good mod but yes even on low res my PC still takes a big hit, my card is an ATI HD4850 512mb, processor is dual core 3.5ghz and 4gb DDR2 kingston HyperX ram, hoping to update to a new video card but wouldn't be for at least 6mths yet!

so a lower version would be great!

I am about to try your interior mod, looks good from the pics!
