please show me/us what goes with what ?

My guess is ...

Game Effects -> GPU with little CPU
Object -> GPU
Particles -> GPU with little CPU
Post processing -> CPU
Shading -> GPU
Shadows -> GPU
Water -> CPU with little GPU
Motion Blur -> GPU
High Res-> MEMORY

Yes, the CPU is pretty useless at anything to do with graphics processing but good for AI, physics. Vram is usually used up by, high resolution, textures, Anti-aliasing.

^incorrect my friendo, having a kick a$s CPU also replaces the places where GPU's struggle, like i posted earlier, I outpaced a 580 with only 768mb of vram, and only 2 460's graphics cards, CPU's and GPU's depend heavily on how the engine of the game was designed, GTA is considered CPU heavy, for god knows what, on the other hand, games like metro 2033, rely dependently on a GPU, for rendering textures, some engines have succeeded in "impostering" certain traits of games that rely on CPU's, like physics, which eliminate the need for processing power, those moments are sometimes just replaced with animated textures, thus "impostering" is the term used, the GPU however relies on the CPU to give a map out of wireframe diagrams and where textures go, its a hand in and operation, however, today Nvidia has beaten out intel and AMD in general processor speed, which is why intel CPU's (and AMD) bottleneck frequently and cannot keep up with graphics card. ATI is tagging along

sorry for the lecture, was trying to get the point across. D:
so.............. the summary of all this, it depends on the game..........

Yeah.. it has alot to do with the "type of game engine" and your "pc setup". One players computer may use their CPU more for certain things compared to another players, just depending on how much memory your system has, type of graphics card and it's capabilities, and type of processor and it's capabilities. Over all in a nutshell though, you not to far off... but it varies from system to system. You'd be surprised at exactly what a big difference can be made by changing one piece of hardware in your system.

Example, your harddrive, which is by far the "slowest" piece of hardware you have, it too effects your gaming experience, especially when it comes to load times. I used to have a RAID 0 setup with two WD VelociRaptor 450gb Sata-III harddrives, it was fast and I was truely pleased with it, then I went to a "SSD Drive" and realized how badly my harddrives were holding me up. My load times are now 20x faster and my games run soooo much smoother. That one small change increase things wonderfully for me and made my total gaming experience completely different. Now I can't even imagine "not" having a SSD drive!

There are alot a variants for each setup. You can have a nVidia GTX 580 graphics card, but still get slower game play than someone with a GTX 560 Ti if the rest of your system can not put out so to speak.

Took a few years before games started to use the cores of my i7 920.

Have a Q8400 and games STILL don't use all the cores... should've got a e8500

You've missed the point. The CPU just processes information given to it from the GPU, it doesn't process the effects he listed, that's the GPUs job.

Game Effects -> GPU

Object -> CPU, but tessellation is done by GPU.

Particles -> CPU

Post processing -> GPU. This is one thing where we can definitely say it's a GPU job, because post proc. is basically AA and AF other filtering. I can't believe anyone thinks that's done by the CPU...

Shading -> GPU

Shadows -> CPU

Water -> CPU

Motion Blur -> GPU, but can maybe impact on the CPU was well, from what I've heard....dunno...

High Res-> GPU

What you've got to remember is that the GPU generally doesn't calculate anything. Infact, I don't even think the GPU 'knows' that what it's putting out is a 3D model, or anything about the equations involved for it to make sense as a 3d environment. If the image that you're looking at is complex, with lots of pixels that are different colours and in different orders, that's where the GPU has to work. Obviously, crysis 2 does feature tessellation, and that's a new thing, but even POM is still a CPU job. All the GPU does is pump out polygons.

I can't imagine the GPU goes through the CPU, then the CPU sends the frame back to the GPU, before the GPU sends it to your monitor. That would create lag. I think you can liken it to a production line, where the CPU calculates the physics, in a wire mesh sense, this is a basic bare bones 'image', then it hands those frames onto the GPU for the GPU to render in high res with eye candy.

You've missed the point. The CPU just processes information given to it from the GPU, it doesn't process the effects he listed, that's the GPUs job.

There you have it, the full summary, there is no way any single game engine processes any of these in the same format, doing so would cause copyright issues, or, just be the same engine to begin with, unless hes talking specifically about crysis 2.........and FYI, some games run very very little on a CPU, Unigine only uses 10% of CPU power, solely because its a GPU benchmark, and stresses lol, the GPU's, proving a "game" can run and thrive without dependency on the CPU
