so epic is saying that the 6800 ultra and x800 xt pe can not run unreal 3 at decent frames? does this mean that unreal 3 will only be playable by next generation high end cards? because i find it hard to believe that the next generation mid and low end cards will be faster than a 6800 ultra or x800 xt pe.

1 or 2 generations until the game is released.

still they are locking out a large portion of the gaming world. most still have a radeon 9xxx or geforce fx or even geforce 4 ti cards. sales are going to be small i think.

They dont seem to care, they just want to make the best possible engine really.

And hey ok, go for it, as time has shown the Unreal engines have been hugely popular. So it will have a massively long life span.

Well they may have said that but the fact is there isnt a cpu that is fast enough to even push my little 6800 gt to see what it can do.

Your 6800GT would be gpu limited with an fx53, let alone an fx55. The only video card setup now that will be cpu bottlenecked by an fx55 is a 6800U sli setup, and even that wouldnt run the unreal engine 3 at even 20fps at max settings.

all these numbers people are posting are speculatioin...Epic or whoever is creating the engine may or may not optimize the engine for older cards, so who knows if the 68's/x8's will be able to run the game at ~30fps @ decent settings or not....its just how technology works, can't be stuck in the same gen and technology forever. I'd hope that by the time that the Unreal 3 engine were utilized that we'd be in a new gen of technology.

Well we know the X800 wont run it as the engine is based on PS3 code, nothing under that is being used. And the X800 doesnt have PS3.

I am sure these cards will be able to run the game, but not as the developer intended. My slow poke 8500 runs Doom 3 at 640 x 480 all low detail with no DX9 effects. If Unreal engine gets DX10 effects in there and so on, a minimum 512mb videocard with much more processing power will be required to run at max detail settings just like DOOM 3 requires now. But that doenst mean that users with GeForce 3 cards cannot play doom 3. It's just not smooth, and with low quality detail but still playable. Either way, most users with high-end cards right now will probably upgrade by 2006 since dual core will be in full swing and Longhorn will be around the corner, as well as the adoption of BTX and DDR2, and PCIe becoming mainstream. The unreal 3 engine does seem complex. I read that 1 character in the game is made up of more polygons than the whole Level in the original Unreal. Also both videocard companies will likely go through 2 full generational leaps (1 per year), or at least 1 full one and a refresh. When a refresh arrives, usually the prices fall slightly so ppl would be able to pick up R520 for $300 or so by 2006 (or less). Why worry about problems related to playing a game that isnt going to be out for 2 years?

Exactly. I mean the GT is an extremely fast card now, and it would be faster if it wasnt cpu limiting it. Epic might say that ur shiny new $400 video card is gunna be junk in 1-2 years, but i disagree. I mean the new video cards coming out next year are gunna be fast and powerful and watnot, but how much are they gunna cost? I think the GT or Ultra will be enough to play any U3 engine based game coming out. I mean at medium details eu get
30 fps averag, and that's playable . And i'm sure with newer DX's and drivers the performance is gunna go up quite a bit more. And not only that, but if my new GT can last 2 years, i'll be happy! By that time i can upgrade to BTX, DDR2 (when it doesnt suck anymore), SLI PCIe, and the other stuff.

Games like ES4 are what i'm looking at too, and from the screen shots i've seen in game informer, it looks like the GT and a good ol' 3400+ are gunna be plenty to handle that at the end of '05.

I want my comp to last for a while, and even though the new games are coming out within the next 1-2 years, i believe i'll be ready!

but then it all comes down to what people percieve as playble, certainly 30Fps in a game based on the U3 engine...most probably a Unreal tournament, will be too low for most

This is the same "DOOM 3 WONT EVEN RUN ON A FX5900!" crap that was going on months ago.

When the game comes out, itll support every gaming card out there that you can buy for more than $100.

Well, 2 years from now when we finally do see unreal3, a radeon 9xxx or geforcefx or below are all going to be like a geforce2mx is today. If you are still using those 2 years from now you clearly are not keeping up with the industry. I personally upgrade slowly. Onboard > Voodoo5 > Radeon 9700 PRO > X850XT PE

But even then, I keep up with games fine. In 2 years will I upgrade? Probably not, I'm looking at a new solution. OCing.

Ive got Nexus: The Jupiter Incident, it requires a DX9 card to run, tho it can run on DX8, but it wont let me run on DX9 because i dont have that hardware capability. Just like HL2 wont let me go any higher than DX8.

I cant remember where to look again, but where i found it, you can actually find out the limit of your cards compatibilty with DirectX, my ti4200 can only go up to DX8, even tho the software i have is DX9c, it doesnt help all that much, because my card will ALWAYS default to DX8 because it doesnt have the extra features to run DX9c.

At the moment GPU hardware is compatible with DX9c, it cannot go ANY higher. So simply it wont run DX10 games.

Doom 3 is simply to run on systems that old, because it supports the use of OGL 1 and OGL 1.5, and thats as high as it goes. Theyve made it compatible with older cards by putting those pathways in, Just like HL2, it can run DX9 cards, but it has extra pathways for cards to run AT DX8 and DX7 also.

Ppl are saying this is only DX10 compatible, not entirely true, its actually compatible with DX9c also, because that allows PS3 code to be used. In fact any GPU with PS3 capabilities can actually run Unreal 3, as to the reason why the 6800U can also run it even tho it has no hardware compatibility with DX10.

This engine is BASED on PS3, VS3, SM3, the engine is built upon those things, any DirectX that supports that, will indeed work, as the base code will run ok.

One thing is, in the trailer for Unreal 3, they used a HIGHLY Overclocked system, CPU, RAM, GPU were all heavily overclocked, and that was only helpful to play the in game trailer at like 20FPS with max details, so the ppl who dont overclock are doubtful that they will be able to play this game on it with reasonable FPS. Maybe SLi, but we dont know how well SLi will scale with Unreal 3.

I wasnt trying to flame, hey i have an X800....

What happens when we all switch to Windows 64? Will that and the addition of better drivers help with the frame rate?

Honestly though, after looking at the game design I can't fathom why the Unreal 3 engine would be that much more straining on graphics cards than Doom3 or HL2. The graphics quality looks very similiar to Doom 3 and the physics engine sound very similiar to the HL2 eninge. I think it's a marketing ploy to hype the game and generate pre-sales publicity.

They were also playing on highest settings to show it off. Nobody can't play Doom3 on highest settings right now either.

This is the EXACT same discussion we had before Doom 3 came out. It runs fine on current hardware and last years.

I know by '06 a lot of people will have 6800's or lower still and if they cant run anything using unreal 3 engine then they wont buy it and Epic will lose a lot of money. I dont think they wanna do that.

I mean, i know this is different, but my friend with an athlon XP 2000+ and a slightly oc'ed GF4 4200 can run HL2, Doom 3, and other games while still looking awsome and being very playable. He bought all this about 2 yrs ago. Just think about it...

Yah, it's prob some hype to make sure you go out and buy new crap. What it really might be is some idoit in forums like these trying to scare people. My old 5200 and 1800 athlon ran far cry well on decent settings are you telling me my 270 dollar card can not run the unreal tournament? Please, people need to have more faith in their hardware then what some nvidia spokesperson or forum member says.

Where do you idiots come from? Anything done in PS3 can be done in PS2 on top of that anytime a card cannot run a particular shader it will downgrade to the equivalent lower shader.

Im an idiot for saying that?

So when u put Far Cry to PS3, the X800 downgrades to PS2. Ok then, BUT IT HAS A PS2 PATHWAY for it to run on.

If the Unreal 3 Engine is BASED on PS3 and they dont put any PS2 coding for it to fall back on, IT WONT! JEEEEEZUS, And who the stupid one, hmm, maybe THERE IS NOTHING TO DOWNGRADE TO!

Ive been reading through a lot of info on the Unreal 3 engine again.

DirectX9 seems to be the minimum spec for the engine. Also they are basing their engine and optimizing the engine for PS3, but i also read that they dont like using fallback shaders and as they happen to be basing it on PS3 going back would be classed as fallback, so i dont know if they will make PS2 stuff as DirectX9 supports that. So maybe, maybe not, dont know on that point.

But from what i read, they will be supporting most of what the X800 has, like 24 bit FP as well as 32bit FP, but the 24 bit has a few bugs as they are using native 32bit FP coding so it looks wierd in 24bit, so maybe they have that fixed.

From all the info i read tho, the engine is definitly aimed at PS3, and it also states that its using PS3 features in the official website, tho, it doesnt say anywhere in the official site it is a bases of its engine.

Have a read through these, to get a better idea
