when using AEFS2 with unrestricted FPS.
If I set FPS limit to VSync ( I don't use this one because it causes lot's of stuttering ), 120 or 240, everything is fine, but if I set the FPS to no limit, my PC starts making a strange high pitch noise, as if it was music, changing when I change views or menus... It is really weird, and apparently goes OFF when I START the flight ( or the sound of the aircraft overrides it ? ) ...
It's not the graphics board fans.
Coil whine?
Ya Da Man HiFlyer!Thx!!!
Please answer my button assignment quiz thread too 
2 things: yes, key assignment and parts of the GUI has been an issue since minute 1, they seem completely offroad with their solution.
and: what is vsync anyway? i have activated it, but i have no clou what it is, anyone explain this.
If your monitor is set at 60 Hz any output from your graphics card above that rate will show ugly split screens unless you spend a lot of money or use various settings to avoid this effect. I use adaptive VSYNC in my graphics card menu and VSYNC off in FS 2. It stops the card from sending output above 60 Hz and is a good cheap option. There are hardware fixes which force the card and monitor to match each other, they are more costly. There is much more to this if you look into it.
