Surely this is what I exactly expected from here.
We can't see each others system, so it is okay.
That seems to prove that GSX is not the problem.
But this is not right. It only shows that *overall* CPU time can be used by FSX because less program has been loaded.
Also, the programs I run usually does nothing like couatl.exe.
It does not prove GSX is the problem or not, also other programs.
The only one thing I'm suffering is system goes extremely slows down when I run GSX.
It disappears as soon as I restart couatl from FSX menu.
I'll look into this what I can do - including your recommendation, too.
Until then,
thank you for your help and it was helpful that couatl.exe does not use any cpu time.
I'll take a time to find out what is going wrong on my PC.
*quick update*
Found there is nothing wrong with CPU time.
I think usage of CPU goes up and down by FSX periodically. (from 1 to about 40%)
Couatl.exe don't use CPU time.
And STILL can't figure out why whole system goes slow down when only GSX is active..
I'll dig into this more..
*edit 2*
I tried to reinstall GSX because everytime when updated within FSX, showed up install has stopped, etc..
But chrome blocked setup file as it is a Malware..
*edit 3*
I think it is caused by GPU throttling.
As I said earlier, I failed to record the video because it shows stuttering to me but not to recorded video.
Well this might be the reason that happens..
Despite I don't use any graphical enhancements, it is so sad that this happens to me.
I'll stick to this situation for a while and will check my Video card is defected..
Thanks!
about image:
1/3 portion shows FSX+GSX. (99% GPU load)
2/3 portion shows FSX. (GSX reset, restart couatl, 80% GPU load)
3/3 portion shows all closed. (0% GPU load)
*final edit*
The problem never happens with default aircrafts..
Here is another GPU-Z screen.
Thank you for your patient and helpful resources to make me where to find a problem.
