Ne post uit een forum: het ging over da den 360 crysis zou kunne draaie of niet!
I doubt it would have the same texture resolution, but a lot of what is being done plays into the 360s strengths. e.g. A lot of geometry-foiliage can be processed quickly due to unified shaders (vertex data tends to be bursty which tends to benefit the design). HDR and AA are negligable in performance hit. The soft shadows is something else the 360 does well--this is a task that relies on shader performance + Dynamic Branching. Note how the X1900XT goes from a 20% to 60% performance lead over the 7900GTX when soft shadows are enabled. Xenos has a slightly larger batch size than the X1900XT (64 to 48), but the general rule applies. The 360 also only has to targer 720p.
On the other side the CPU could be an issue. Multithreading is hard work and very few have done well at it; having the destructible plants and buildings could pose a problem (GRAW physics effects says it is possible... but every dev is different).
I honestly don't think most people understand much about how graphics in these things work. e.g Xenos only has 16 TMUs @ 500MHz. The X1800XT has 16TMUs @ 625MHz. If a game is texture-heavy the X1800XT is going to blow by Xenos. In certain situations if it is not handled with care it can be as slow as a 6600GT (Xenos has only 8 ROPs... although they are very robust and tied to the eDRAM if they are not handled correctly you are going to KILL your renderer).
Xenos is not a miracle chip. What it is, though, is a chip designed "smartly". There is really little point to continue increasing the TMUs. Sure, it helps in "Super DX9" games, which are really just DX7 games with some shaders tossed on top. News Flash: Oblivion was the FIRST game to require SM2.0. Yeah, scary. It is a 4 year old API and we are just NOW seeing games require it.
Where Xenos excells is in shaders, specifically SM3.0 (plus the extra stuff it can do beyond that spec). How many PC games use SM3.0? FEAR, SC:CT, Far Cry, Oblivion... uhhh.... maybe a couple others. How many build around it? 0. All these games are DX9 games with an added path for some "extra goodies". And we wont be seeing any SM3.0 heavy games any time soon... maybe never. Why? Because while Nvidia owns 88% of all SM3.0 GPUs, their SM3.0 performance SUCKS. It is 1/4th the speed of the comparable X1000 series GPUs in heavy dynamic branching.
The issue is a paradigm one. Xenos IS NOT A PC CHIP. It was designed for the consoles and is much more future looking. Sure, a couple games have used HDR+AA, and most now have 4xAA. But by all developer accounts they are hardly touching the Shader ALUs. None have used the hardware tesselation or HOS. Until recently developers were stuck using the manual tiling and could not use XPC. A number of titles, mostly ports of Xbox engines or PC games, could not use the eDRAM because they did not do an early Z-pass which made them incompatible with the eDRAM tiling.
But as much as we can knock the 360 in areas (I had a post this weekend outlining all the issues MS has hads and continues to have), some of you PC fanboys are waaaay too biased. Sorry to the poster above dissing GRAW, but I have not seen a FPS that nice on the PC yet--and the PC media so far looks like a big step below it. The fact the explosions are way above anything we have seen on the PC version w/o an AGEIA card. Next look at something as simple as Kameo or PGR3. No racer on the PC gets close to PGR3. Further, Kameo has over 1M particle physics-effects on screen at a time without slow down. You CANNOT do that on a current PC--the 360 chewed through it. And some filtering issues aside, CoD2 runs very, very well on the 360. Much better than a $300 GPU.
There will be games designed for the 360 from day 1. The new PGR, Forza, Halo, etc. These titles will use the eDRAM correctly and move the work load away from the TMUs to the Shaders. Those who are judging the software by the early PC/Xbox ports can dance all you want, but this is no different than when the PS2 got a lot of PS1 ports or when the Xbox got a number of PS2 ports. Its not like the Xbox 360 has not provided high-end PC graphics on a cheap console--because it has.
Obviously the 360 wont be the best hardware on the market. The X1900 already has more raw PS power; the R600 will have Geometry Shaders, more shader performance across the board, more effecient shading model, and resolve a number of issues Xenos has. Of course the 360 has eDRAM and 100% speed HDR which resolves a number of pipeline stalls, and it is a closed box with a very close symbiotic relationship with the CPU that has 2-4x as much realworld vector performance per core over an x86 chip.
Ultimately we are seeing the "dead end" of the DX7 approach. DX8 and DX9 just added more robust shader models, but ultimately DX was designed with progrability as an extra feature--not the core. Further, the hardware and engines were designed with a 1:1 TMU

hader arrangement. I can count DOZENS of games where the X1900XT is less than 5% faster than the X1800XT. The X1900XT has 3x the peak shader performance, so why no improvement? Because the games are NOT suited for the extra shader power.
But would anyone in their right mind diss the X1900XT because in many games it barely edges the X1800XT?
Of course not, because when games start using more Shaders and heavier SM3.0 paths the X1900XT is going to fly right by the X1800XT.
And that is what we have with Xenos. Yeah, an X1800XT is better for CURRENT games. No doubt. But once you shift the work load to more shader intensive tasks -- like soft shadows -- the two chips perform completely different. There is a reason the X1900XT is neck and neck with the X1800XT in some tasks, yet the second you push on shaders some the X1900XT runs away.
Toss in all the features the Xbox 360 has and you can make some really great software. But basing its performance off of SM2.0 games designed with PC (or Xbox!) hardware paradigms in mind is really foolish. The PC is a great format for those who have the money. But reality is that PCs are expensive and get fewer games and even fewer exclusives. For those of us who like mods, Mice, and like spending crazy money it is a great platform. But the "PC is always better" arguement is pretty much wrong.
