Hope this helps, Rob 1) Do you see the airplane begin to wander in 8x+ time compression if you use PMDG's Auto-Time-Compression feature? Yes 2) Do you see the airplane begin to wander in 8x+ time compression if you manually set the time compression using the FSX menu or key commands? Yes - using key commands. Have not tried menu 3) Do you have FSUIPC installed? No 4) Have you tried deleting your FSX.CFG file and letting it rebuild? Yes - problem still exists 5) Do you have Lockheed Martin Prepar3d installed on this machine? No 6) When the airplane begins to wander, watch the HEADING ROSE on the NAV DISPLAY very carefully. Is it rotating in the proper direction and remaining in sync with the airplane heading? If not- we need to know. Heading rose is not in sync and may move in opposite direction. For example, aircraft banks left but heading remains still and sometimes turns right.

I am also experiencing the same problem. This happened to me while flying tutorial 1. I hope the following information will be of use: 1) Default FSX Weather with clear skies preset theme 2) PMDG house livery -200LR. (Have not checked other liveries) 3) SP1 was installed directly on top of RTM build. 4) Turbulence effects are disabled in FSX settings 5) The issue with 's' turns is most pronounced at 8x and 16x compression. (Engaged using CHR clock button). 6) Plane performs as expected when time compression is not used. 7) Auto step climbs and 'pause at top of descent' are turned off. I Hope this was helpful

Thanks to everyone for your kind advice. I have come up with two potential system builds for FSX, again with a budget of £600. Please note that this budget includes windows software, monitor etc. The two systems basically boil down to the following: 1) i3 4340 3.6Ghz, GTX 660, 8 GB RAM 2) i5 4570 3.2Ghz, GTX 750 Ti, 8 GB RAM 1) http://uk.pcpartpicker.com/p/6KcJmG 2) http://uk.pcpartpicker.com/p/mtQXYJ My question is which one of the two builds will provide better performance for FSX? Once again, I will not be overclocking the CPU and budget constraints mean that there is very limited upgrade potential to either of these builds. For example an i5 with gtx 760 will not be feasible. Thank you for your consideration

If I can find a good deal, I will definitely buy a k-series processor. However, I do not plan on serious overclocking, auto overclocking features like OC Genie seem sufficient to me. So just to confirm, a non-k series cpu like the i3 4360 is absolutely impossible to overclock and that even if I consider the remote possibility of overclocking I should buy a 'k' series? Thanks for your help

Ok, the gtx 660 seems to be reasonable. I am not interested in overclocking, I only put in the 3570k because it was for some reason the cheapest i5 processor at the time. Also, will 'downgrading' to an i3 4360 at 3.7Ghz yield a significant drop in performance? Is there any real difference between dual core and quad core for fsx?

Ok, I've taken onboard some of the advice and I realise that at my price point I wont be able to build a perfect rig for FSX. However, the reality is that I cant afford £600+ on a computer right now. I've tried to make a compromise with the following build: http://uk.pcpartpicker.com/p/V3nPK8 what do you think?

ok, thanks for your help. Better get saving then...

Hi, I am looking for some advice on my first FSX PC build. I am under a strict budget of £600. Here are my main specs: CPU: Intel i3 4340 @3.6Ghz GPU: Nvidia GTX 750 1GB RAM: 8GB I'm planning on running FSX with ASN and PMDG 777 at 30fps. I do not plan on using any payware scenery but may use some freeware HD textures for clouds/sky etc. I understand that FSX is quite CPU intensive and it doesn't seem to take advantage of extra cores, so is there any significant benefit of upgrading to an i5 if i don't plan on overclocking? Also, is my graphics card sufficient for my demands and should i consider upgrading to the 750Ti or equivalent cards? Any advice and opinions will be appreciated, thank you.
