Hi All,I have just upgraded my PC to the following spec;AMD FX53ASUS SK8V Motherboard1GB DDR400 RAM2 Maxtor HDD'sAudigy 2ZS/Latest Drivers19 inch Sony TFTRadeon X800 PRO 256MBLatest Omega Graphics DriverXP Home SP1Installed FS9. I am getting frame rates that I am happy with, ie 19-25 with all settings maxed/FSMeteo/UT at 90% at LHR. The problem is I'm getting stutters a lot of the time. I have done all the usual FS9.cfg tweaks I know of but just cannot get rid of them. I did try reducing some of the FS9 sliders and although frame rates increased the stuttering did not reduce.As I sold my soul to good 'ol Nick to get this rig I would not have expected this. I would be grateful for any further advice to try to solve this 'cos then I would be TOTALLY happy with life again.CheersMike

mike, had the same problem awhile back when i upgraded. i'm sure you've already done this but if you haven't try defraging your machine. it fixed mine. hope it's as simple as that. good luck. william

Mike:You might want to do a search of the forum on this topic. There are several different things that can cause stutters, even in high-end systems.Also, if you don't already use it, consider downloading Ken Salter's FSAutoStart program. It allows you to turn off programs, before launching FS9, that can eat up cpu time.Also review some of the topics concerning virus protection software. Some of these programs cannot really be turned off, apparently. This was a problem I had with my AMD 64 3400+ system. Changing to Avast solved that one for me.Keep searching -- you will find YOUR solution.Wilson

Actually, Ken has made recommendations for most programs. You just highlight a program and look at the suggestion box to the right of the main window.Wilson
