[nvidia's blog] GDC - NVIDIA, AMD, Intel Explain How OpenGL Can Unlock 7-15x Performance Gains - Page 3

Because $100 less for Windows = $100 more for GPU/CPU.

That's i5 to i7 or R9 270 to R9 280X, GTX 760 to GTX 770.

It especially makes sense for the Steambox initiative.

So could this mean that someone running a DX12 game on Windows gets 7 - 15x less performance than a Freebie Linux user on SteamOS ? redface.gif

of course you can run opengl on windows but a.) thats not what i asked and b.) what would be the point in sticking with windows then?


This literally opens up all that graphical progress we thought we should be getting with each generation.. It could mean that an old AMD 6770 running these OpenGL optimisations is close or renders a current game faster than a brand spanking new Nvidia 780Ti running DX11, a bit like how well old console hardware is optimised.

That could certainly be it.

Yay open source! Go go Linux! Get us away from M$!

OpenGL is more compatible with multiple operating systems. This would promote Linux gaming computers.

I believe the 7-15 claim is towards current OpenGL performance which is behind directx for most games.

OpenGL is not that bad.

There some glitches and major slow downs in Linux, but that's most likely a driver issue.

In Linux my 7870 can't handle explosions D:
On the other hand the GTX 280 renders most objects and scenes correctly, except it forget to draw the floor sometimes.

LOL. I thought my GTX275 was bad with permanent tearing (even though vsync is enabled) and stuttering...at least everything get's drawn in. Though with Nvidia retiring the 200s from drivers (read they'll have use a legacy driver soon to be released) soon I may just have to get a new GPU.

While AMD is pushing mantle hard, they can't afford to just sit around idle and get left behind. That's why they're probably taking a one eye open one eye shut approach to this. Same but a lesser degree for Nvidia.

Quite the plethora of choices, Mantle, DX12 and OpenGL.
