My gpu usage in fsx is at most 30% and an average of 20% ( i checked it in msi afterburner.) I have a msi 570gtx with 1.5gb mem. Is this normal? And how can I let fsx use more of my gpu? My CPU is a Sandy bridge 2600k.When i fly i have microstutters when in windowseat view. I think it is gpu related.

I think it would depend on your monitor size and AA/AF settings? But I don't think GPU load is the limiting graphics card factor for FSX if I understand "*******'s" findings correctly. scott s..
