I also have an AMD X2 4800+ (which is only slightly faster than your processor) and I do not see flightgear switching cores while it is running. I can monitor how the cores are being utilized via gkrellm2. The Linux process scheduler tends to keep processes running on the same core to avoid issues with cache coherency and the like. I agree with Heiko that this sounds like the stutter problem. I have found that I can make the stutter problem either very bad or almost unnoticeable depending on how I setup flightgear and my OpenGL driver settings. You might try the following. In FlightGear --model-hz=<your monitor refresh rate> for LCDs this is typically 60. Using either nvidia-settings or nvclock Sync to VBlank = true Allow Flipping = true Disable cpu optimizations = true Texture Clamping = true setting --model-hz and using Sync to VBlank will synchronize both the graphics systems and the FDM and Disable cpu optimizations frees up some cpu resources to help keep the FDM running smoothly. At least that is my theory for why this seems to, for the most part, work. With these setting I only see the stutter problem with doing high speed aerobatics at very low altitudes and even then the stutters are only for a fraction of a second.
