Nvidia can give those techniques specifically to their cards but they should make them open source it is the reason why there Cuda thing will die once.
Tress FX is open source not that it will run well on Nvidia gpu's not because they gimped it for those, but because Nvidia mid gpus lack compute power.
PhysX, Cuda, FXAA and now HBAO all a waste if you ask me.
Cuda isn't just game related you know. Cuda in certain programs is incredibly powerful and useful for real world tasks. I'm sure someone on here can chime in on it's real-world use in programs for things like rendering, ray tracing and 3D intensive programs that aren't game related.
HBAO is also a very nice performing form of AO, which in the overall picture looks very nice and helps realism (very noticable in BF3/GTA IV using Icenhancer/ENB), compared to the standard Ambient Occlusion which can be quite heavy on the GPU, especially if the game is graphically intensive already.
FXAA isn't just nvidia based and is a very useful solution to games like Crysis 3 where you can't afford MSAA or SSAA, but you want to get a good balance between anti-aliasing and fps, which it does very well at. Yes, it can induce a slight blur, but there are tweaked versions that blur less and do a very good job at anti-aliasing via injectors. SweetFx for example can apply luma sharpening, so a user could apply that to their game along side FXAA to help reduce the blur from the post anti-aliasing effects of FXAA itself.
I can understand a part of your point of view if i'm understanding correctly, in that special effects shouldn't be dedicated just to Nvidia or just to ATI, and that they should both run fast and efficiently and both pieces hardware vendors, but sadly Nvidia are quite pushy in that regard and love to get an advantage somewhere. It's more saddening that then those with the opposite vendor of hardware can't use that effect or can't run it well at all near what the true vendor can.Edited by icanhasburgers - 8/21/13 at 6:16pm
