I'm running Demo2 on (see lappy specs below).I've done most all of the tweaks (no texture resizing)I've got poolsize=5000000Fiber whatever whatever at .33autogen below 1k for eachI've messed around with sliders like crazy and I still get stuttering... I feel like I'm missing something in the CFG that is supposed to help with stuttering... is there anything else I can change in FSX.CFG?EDIT: I should mention: Stuttering occurs when turning at standard rate turns. Not ever in straight and level...EDIT EDIT: I should also mention that I'm running at about 80% system memory and only about 150mb of my 256mb graphics (using memstat) so no page file...EDIT EDIT EDIT: I tried poolsize=10000000

I have the exact same problem, with no solution, and like you have tried everything!Ian
