I'm using a 2006 Mac Pro 1,1 2.26 Intel Xeon (x2) with 16GB RAM and a Radeon 5870 1GB graphics card, running Lion OS X 10.7 (maximum OS on this old Mac Pro).
Currently running X-Plane 10.3 64bit, and getting around 20FPS near airports and 30FPS in the clear, with medium/low rendering settings (around 280mb graphics used). The sim works great, and the Diamond TwinStar is my favourite plane, especially with X-Mapper on the iPad.......
Question is... will upgrading to 10.4.x improve or reduce my frame rate?
I'm keen to take advantage of the new X-Plane build architecture but terrified the sim will s l o w d o w n
Anyone tried the latest update on old Mac hardware and seen a significant change in performance?
