Dear all, it might interest some of you here that the last developer preview build of 10.9 Mavericks in combination with 17.09 GW2 patch has improved the performance to the levels that I completely abandoned the Windows client because frankly, there is no noticeable difference between the two. I can now run 1680×1050 with high settings on OS X my 15" base retina and get 40-50 fps on average. Which is basically the same as on Windows. The image quality is rather good.In really high populates zones this drops significantly (to around 15-20 fps in LA during primetime) and big WWW battles can still get laggy, but again – the Windows client has the same problems for me. All in all, I am extremely impressed with Apple’s/Nvidia progress on the GPU drivers. The Unigine benchmarks also show less then 15% performance difference between OS X and Windows, which is a new high in my experience.
Happy Mac gaming for you all!
