Stuttering in VFR scenery UK following CFG Tuning tool

Hope I have placed this in the right place?Hi wonder if you can help. I have been using the tweaking tool and now my flight sim has improved with scenery from Orbix and I can load Normal Autogen with good results, but my VFR scenery of the UK has blurring problems and stuttering issues which it did not have before. I have replaced my original CFG file but this seems to now not be working quite right as it was before the changes were made. I have had to resort to doing a restore point return on my pc to see if that helps. Still blurring issues and stuttering. The blurring may vary. With the autogen off in VFR scenery there are still slight stutters when panning around. I use the TrackTR . I have always run with vertical sync on as I don’t like the tearing and have had good results with other tweeks, Pools etc.I have tried to make a default CFG file but this made things worse. I have tried putting the changes made/recommended from your Tweeks tool to my original CFG manually but still stuttering and blurring. You recommend the controlling of frames from within FSX I am trying to get the program to run the WinRa file. Once this is applied how easy is it to remove if it does not work? Bit cautious with my Pc as I have spent a lot of time and money on various bits/scenery etc.Any suggestions – I have tried what I think are changes to the pools, texture band etc Regards Stewart
