Valve: Linux Left 4 Dead 2 running at 315 FPS

Valve recently announced that it was working to get Left 4 Dead 2 up and running on a native Linux Ubuntu OS. That mission is still in progress, but this week Valve announced that the game now runs faster on Linux than it does on Windows 7.

In the newest post on the Valve Linux Development blog, Valve said that when they started working on the Linux port of Left 4 Dead 2, they were only able to get six frames per second out of the game with a PC that has an Intel Core i7 3930k processor, a NVIDIA GeForce GTX 680 graphics card and 32 GB of RAM. The Windows 7 version of Left 4 Dead 2 went up to 270.6 frames per second on Direct3D drivers.

The Linux team has made a ton of progress and now they report that, running on a 32-bit version of Linux and OpenGL drivers, they were able to get Left 4 Dead 2 running at 315 frames per second. How is this possible? The blog states:

It appears that it’s not related to multitasking overhead. We have been doing some fairly close analysis and it comes down to a few additional microseconds overhead per batch in Direct3D which does not affect OpenGL on Windows. Now that we know the hardware is capable of more performance, we will go back and figure out how to mitigate this effect under Direct3D.

There's still no word on when the Linux version of Left 4 Dead 2 will be released.

They are playing one hell of a long game by porting to Linux. Frankly, I don't see how it makes sense.

It does:
Valve and a few other companies are bashing Win8 like your typical 'we dont like change' breed of idiots. Valve also doesnt like that the Xbox/GFWL store will be part of the Microsoft store in Win 8, and is pretending that win8 sucks and playing on the 'we dont like change' idiots irrational hate of the OS to make it seem like Linux is the future. I have no opinion of Win8, but its not the 'catastrophe' tune valve is playing to the media. This news release by them is nothing more than a followup to that. They are terrified probably of the sales drops from the Win8 store.

HMM and i wonder why so many moons ago ... mostly all games years back where opengl hmm good old 3dfx

Many moons ago openGL was the only real graphical option, unless developers wrote rendering options for specific cards, but was a pain to code for games. Then 3DFX made Glide then so things got better. But then Direct 3D became really good and was doing things better then openGL. Only Id has stuck with OpenGL for there games and if its been made for Mac.

Though I think OpenGL has now become pretty equal with Direct 3D these days, which is good as Microsoft need competition
