yeah i got shit on a ti 500 to man this is the deal:
the dled SP Demo did not have compressed textures which means that it does not support high rez and thought it runs on High texture detail it chugs cuz it encounters alot of texture swaping
the second reason may be one of pre cahceing. This lvl is 1 in a serise and certin things the game calls for are not in the demo so it chuggs...there is nothign u can do about this
for the 1st one change the texture detail to medium, that helps and reduce the rez to like 640x XXX to get better resutls.
THIS IS NOT GONNA BE A PROB IN THE FINAL GAME....DO NOT WORRY!!!!! (2015 SAID SO)
And yeah, i would imagine that the SP demo on the CD from computer gaming world (out Jan. 8th) should have compressed textures...i would imagine..might not but still u will nto have any probs
