I saw your post. I have a 750 mb 8800 GTX Nvidia Graphics Card. I am impressed with your frame rate using Linux. I am thinking of going to Linux. I would be interested to know what motherboard, and CPU you have. Also, how much ram memory do you have. I have an older computer using a dual core intel CPU and 32 bit Asus motherboard that is 6 years old. My CPU is 3.4 Ghz. I was thinking of building a newer computer, but wonder if I use Linux on my current computer, would I get 30 frame rates per second with very high x-plane resolution. Appreciate your input. Thank you.
