I'm gonna have to start saving all this stuff (answers) when it comes to problems. Your flying along --FSX of course- unlimited frames are 50 -60 no problem there but every so often there's these not to big square white little blankets that pop up for a mili second and go away, i read once what causes this but can't remember. Any ideas?--- Louis

Over taxing the videocard, maybe overheating too.Limit framerates and you may find it goes away.IAN

I'd also like to add that when you limit your frame rates, use an external FPS limiter with the in-game FPS limiter set to unlimited.

Ok thanks i'll give that a go. I just read George Klien's book on Elvis my best man LT. I went to Memphis and had supper with the memphis mafia last year at Alfred's on Beale Street -- was a blast .

Hi FolksLouis8 -Sounds like you're using RTM or SP1if so they're the initialisation of effect's textures,which initially display as a white square,before the effect's texture is displayed.In SP2/Accelerationthose squares are now displayed as black.Reducing your FPS or slider settingswill reduce the amount of time they are displayed for.HTHATBPaul

I wound up deleting my fsx conf file and built a new on so far so good. You know how it goes a teak here and one there and pretty soon you don't know what the heck you did. but i'l try what you said and i do have accelerator. For a system like i have in Orbx PNW she's pretty sad, coming out of Concrete she's at 20 frames and major stuttering ,, pretty fed up with this.
