Hi! I have some problems with my fps when using CRJ-200. Usually my fps is around 60-120 with basic xplane aircrafts, but with crj-200 i get around 20-30fps, wich isn't bad but it's still no as smooth as i would like, plus the PFD and ND have some stutter too. The weird thing is that sometimes, with same settings and weather and airport i get solid over 40fps. I just don't understand how one time it works like magic and next time it hardly works at all. My specs are: Xplane SP3 Processor: Intel Core Quad CPU q6600 @ 2,40GHz Memory: 4,00 GB RAM Nvidia GeForce GTX 260 896mb Windows 7 64bit It's not the newest of computers, but run every new game just fine.
