I was flying 512 ods in the north (mountains) twice and after quite some flying distance something strange happened both times
THe terrain textures turned very low res, then some tiles were missing and then only white came up and no more terrain. I still crashed into ground. When pressing esc i ctd both times.
check your textuer.zip for 16bit images
the first problem tou had sound like a 16bit image somwhere, not sure though.
you can easely check for them by unzipping texture.zip and order by size.
if a tile or a group of tiles are reletively bigger then others then they are 16 bit.
No definitly no 16 bit in H tiles and the rest is runtiles made. It also just appears after a certain flying time - dunno if time accelleration makes it worse. Weird
It actually sounds like a hardware failure on your system.. your upper level ram may have problems. If it is always when you enter ther ram usage of 250mbs to 300mbs then you have a back stick. I would suggest you think about testing your ram.
hmm not that i would know of - at least the proggies dont crash - even if i use all memory and other things than falcon - also this is related to just a specific f4 theater. hmm...
And hey i spent the money to grab some quality RAM
