I am using a slightly modified PX1 circuit board from Martin for a golf project I am working on. I have had custom software written for me that integrates with this circuit board. All prior testing of my software and the PX1 has been done using my laptop with a mid-range graphics card. Because of this, my modified Red Chain software could only be played on medium graphics settings. I upgraded to a desktop with a 2GB Radeon 7850. I can now max out the graphics settings and the ball flight is beautiful. The problem is that when using the exact same GSA control panel with the same settings, I occasionally now have swings with no ball launch especially at slow swing speeds. I never had this happen with my old set up. I did downgrade from an i7 processor to an i5 but I can't imagine that this is the problem. Any GSA experts with thoughts on this?
