google translate is not very good on your post, hence I'm not sure what you mean.
I wanted to say that:"I might only buy native OpenGL games." I'm running RAGE etc. perfectly with WINE (and windoze steam). So why the heck should I pay more?
I'll try to rephrase what I said.
The difference between "native" OpenGL and Valve's translation layer is artificial. It doesn't exist. With a fully customized and optimized translation layer, there is essentially no loss in quality. L4D2 actually runs better through the translation layer to OpenGL on Ubuntu than in its D3D implementation on Windows.
I also don't see why you think you should "pay more", because you're not being charged extra for your Linux versions. But if you're adamant about it, well, your loss.
I don't know about RAGE, but Valve is not using a fork of Wine. Someone might have compared the solutions somewhere, but that would not be a fair comparison and it only creates confusion.
Simply put: the Source engine will run natively on Linux.
So, you're saying that programmed in Windoze D3D works, with Valve's layer, on all main OS?
Interesting, but that's surely not done in some weeks. Hence it must be a Wine fork, unless otherways proven!
Well ID had such years ago? As Doom etc. are opensourced, it might be derived from that?
Only time will tell.
However, with Valve being pretty pissed off at Micro$oft because of their Micro$oft Store, it's likely that EA & others will follow, which would in turn mean more games available for Linux than just Valve games.
Either way, things are looking good!
Also, with the Surface Tablet Micro$oft is turning the OEMs against them.
Window$ 8 could very well be the opportunity that Linux has been waiting for.
All I know is that I know nothing....
