Hi,

A few things:

1. The drivers are made by, well, not us. So I can’t really comment about what can be done with the drivers; I don’t have the source code.

2. The use of GL 2.1 vs 4 is due to Apple not supporting the compatibility-API – to get GL 4 on Mavericks we need to rewrite a bunch of code. I ahve a blog post I’ll get to later about this, but the short of it is, to get GL 4, apps on OS X have to do more work, and we are doing that work.

3. The GL version says NOTHING about the actual performance of X-Plane with the driver – that’s a giant distraction. Every feature we need for full speed operation is available via GL2.1 + extensions, available on OS X.

But that doesn’t mean that the fps gap is okay. If there is a big gap between fps on Windows vs Mac, that is not good.

There is one thing you can do to help: run the fps test on Mac and Windows with latest drivers on both (Maverick, and latest IHV drivers on Win 7) and send the log.txt with the fps testes to me, along with an Apple system profile. I can then file a performance bug with Apple.

If you are seeing faster fps on Win than Mac on ATI, I’d definitely like to see it, as the Mac ATI drivers have historically been very fast.
If you are seeing faster fps on Win than Mac on NV, please note that instancing isn’t working well for us on the NV Mac drivers right now, something we are looking into.

Cheers
Ben

Would it be possible to make some better graphic drivers for Mac OSX MAVERICKS as they are for windows..?
I mean under Windows 7 it uses open GL 4… Under OSX it uses open gl 2.1….
then performances are a lot better under windows…

it is so bad for a mac user to play x-plane under windows 7/bootcamp…

So what’up about those things..??

Thanx
