One of the advantages of EDRAM is when reading and writing the 'same' render target/texture - on 360 it's different ram - you retain the previous state (the last resolve) of your texture in RAM and you can do what you like in EDRAM. On systems without EDRAM you must swap buffers, and possibly begin with a 'restore' of the previous pixels if it's a partial update. Funnily enough this 'restore' is another one of the downsides to EDRAM when updating render target content (when you can't limit it to a sub-rect resolve).

Well, funny story, but it got lost somewhere. I've talked with Wolfgang Engel about it, and it might appear in GPU Pro 2 and/or as a download. The sample code is in the big download though.

What happened to your "Volume Decals" article that was supposed to be in the book as well?

sqrt[-1], we have to light translucent objects, but also our pre-z pass is quite limited for performance reasons. Our occlusion culling removes enough stuff for pre-z to not pay off in general except for very near objects, so the pre-z pass only has a few stuff in it.

Hi Humus,

A friend of mine saw this post of yours and thus decided to try resurrecting one of my old cards, and he did so successfully.
Before the operation, the card would make his PC crash shortly after booting into the OS. But after the operation, he was able to run FurMark for 2 hours without a problem.

Good recipe, chef :-)

u can also run anti-aliasing on the CPU with the xbox360, u can use the VMX128 to accelerate filtering and move anti-aliasing fully onto the CPU.

the CPU PPC970/VMX128 is better at doing DSP tasks than the xbox360/PS3 GPU's

Hi,

I am not a big fan of your solution. If you use a real class with a real constructor between the markers, it will erase any wanted initialization. The two introduced member will change the size of the structure and you will also initialize padding between two members of different alignment that should remains untouched
