Hi Guys,Tried traffic at 0%. Made no difference. I checked the running processes just in case something untoward is being fired up when FS9 comes in. There were 157 modules in the FS9.exe process! Quite a few were gauge files so I guess that's normal. Nothing in there looking at all suspicious though. On a new tack I decided to pull a few scenery sliders back and a degree of smoothness has returned. In fact I can now fly around Scotflight's Edinburgh airport several times without descending into stutter country. But I've lost some scenery definition so it's a case of being given with one hand and taking away with the other. Maybe I should go back to FS2000 - should perform like a dream on a P4 3Ghz!Argghhhh!AndyB

Your porbably right about fs 2000 on a P4 however it might turn out to be a bad dream go with fs 98 LOL

Hi Mate See if turning the virtual cockpit gauges detail down to low helps,...it has helped me but makes the gauges low res , a way around this is to up the pixel detail in the panel cfg , the default a/c will be 512,512 change it to 1024,1024 ...doing this makes the gauges look like the high setting but with better frame rates .. its weired but does work .
