The only thing that could affect stuttering in our products is the "Anti pop-up" setting in the Addon Manager. If you raise it from the default of 1, it will increase the loading range of smaller objects so, for example, at 4 those objects will load at 4x the distance we programmed in the scenery.
Increasing the value will reduce stuttering, but it will increase also the risk of Out of Memory errors, because more objects will be loaded at the same time.
If you don't see any benefits by raising the slider up, it will indicate the problem is not related to CYVR.
I see from your specs you have only 4GB of RAM, in total. This is really not enough for FSX, because FSX could allocate up to 4GB for itself, but with only 4GB in total, you'll have to share it with Windows and all the other running applications (antivirus, etc.)
Because of the Virtual memory management, even if your total memory requirements exceed 4GB, the PC will not crash because it will use the swap file but, even on a fast SSD, this can't be compared with having real memory, so if swapping happens, you'll see stuttering.
So, the real suggestion would be upgrading your memory to AT LEAST 8GB, and of course be sure you use Windows 7 64 bit.
