Without active Sky's running in the background the game can run fine at 20% to 30% and even then it does happen where it goes to 80% to 90% as an big jump when flying then down again.

Before I haven't had this bad CPU spikes, i7 3930K 3.80 GHz. I able to chnage the affinity mask so that it runs on all cores rather then one.

Active sky's when running!

Rex 4 is loaded and installed as medium settings not set as high. Trying to stream isn't easy as it goes 100% 

Running an GTX 680, resolution 1920-1080-32 Not in preview DX10  when it does spike up you can tell when it lags a little then back down to 10% to 15%

Take off active sky from core 0

how I go about that!

 

affinity mask is set at 248 

well i am not sure. not using fsx and not using am. Just have a look in the task manager while fsx is running without active sky which core works the hardest and then turn on active sky, right click on the active sky process and remove from there the use of the core that working the hardest.

I been playing around, It's now been 20mins with active sky's and the max is 55% mostly statying around in 40% mark.  

Until OBS is on LOL that I haven't tested yet
