Hi all,They're talking over at the Prepar3D.com forum under the hardware topic about making sure the hardware acceleration is "ON". Does anyone know if this is only available on GPUs other than NVIDIA since my "change settings" button in properties is not allowing me access to enter this option and select on. (button is blanked out)Next question is: what is hardware acceleration ? I'm looking into the problem where my FPS halve when using multi screen (3) with Prepar3D. I had no major impact with FSX and multi screen. This is only in high graphic areas like on the RWY at LAX (FSDT) and UT2 AI at the gates using PrePar3D.thanxIM22600KGTX590
