isnt that cascade demo just 1 rock model with some water? seems like a far cry from an actual game. its actually pretty suprising how slow it runs..
Except that it's procedurally-generated rock, with the physics of a large number of water particles done on the graphics card.isnt that cascade demo just 1 rock model with some water? seems like a far cry from an actual game. its actually pretty suprising how slow it runs..
i think a more important question is, will g80 and r600 be fast enough to properly make use of any of the major innovations dx 10 brings, or are they just high speed dx9 chips with checkbox features. i mean if that cascade demo runs at 20 to 40 fps, i dont see g80 having the power to run an actual dx10 game.
That was very interesting. Thanks!
So the way I understand this, this could be used in a real game to create a large world from a mathematical function without the CPU having to really care about it. Are those things that would typically consume a lot of CPU cycles and/or PCIe bandwidth and/or CPU memory and will it free up the CPU to do other stuff in a significant way or will the overall impact be fairly minimal?
If I understand this correctly, instancing on DX9 is pretty limited in what it can do - you send over the definition of an object then a list of parameters that slightly modify it to create different versions. But I think the type of modification is relatively fixed across all instances - it's not programmable. With DX10 you have a lot more flexibility with how you manipulate that object data.
Seems to me an ideal application for procedural generation is foliage. Oblivion currently does this to some degree.Well, you could. The question is whether you want to do that to any larger extent. Procedurally generated art tends to look pretty bland. This is not exactly a new concept either. The difference is that you generate it on the GPU. To some degree you could do this already in DX9. There's also the problem of physics and game feedback which is not neccesarily trivial for real games. DX10 will probably bring a number of games that uses procedural geometry in one way or another, but I don't exactly think it'll replace art work. Mostly I expect it to be used for certain effects like particle systems.
The primary difference being that it is generally frowned upon to show the former to the world in public. Please use the more polite form of this in future. (elbows, noses, bellybuttons).
I don't see why not. The cascades demo runs at fair framerates at 1920x1200 res on my 8800 GTX.
Hmmm, odd. Mine's not overclocked or anything. Perhaps I just have a lower framerate tolerance than you. But on my system, though the framerate is somewhat low, there is no stuttering at all (well, unless I get a screen full of particles from the falling water, but that doesn't happen often).It's chugging like mad on the one I bought today (Asus 8800GTX).

ExcellentI swapped my PSU today for a Corsair 620W, and the framerates in GPU-limited situations basically quadrupled. Cascades runs very smoothly now.
There should some warning from the hardware monitor that something's not quite right, so it's rather odd that never happened. Something for the driver team to take a look at, will point them here so they can see.
Yeah, it's part of the driver (or at least should be, even in Vista x64). If it's something they've moved out to nTune (it's called the NVIDIA Sentinel if I remember rightly) then that's cause for concern. Basic hardware diagnostics shouldn't be part of optional software that might not even work on your system.Where is the HW monitor ? I turned off the motherboard HW monitor (very buggy, Asus makes some great hardware but lousy software, IMHO), but I don't know if the Detonators drivers include some sort of hardware monitoring feature (I'm running Vista 64). Card is an Asus EN8800GTX, I'm using Detonators 100.65.
Well, I think it's a DX10 demo, so I expect it'll work just fine once ATI gets a DX10 part out.is there a wrapper yet for ATi ppl?
