Oblivion framerate is real

HDR + MSAA in 8800 GTX

In my opinion, the result does totally credible the review Perhaps they took the red tablet...

 

I was thinking the same thing. Why would it have a negligible performance hit...especially in Oblivion of all games. Does Speedtree affect it in some way (enhancing the process, or perhaps disabling it on a large amount of surfaces such as their trees...). Would Oblivion benefit from Geometry Instancing? Does it even support it...? Is this an R600 thread?

Ok i'll stop the Oblivion talk. It's pissing me off too.

 

nah ive played games where the g80 is brought to unplayable framerates with just 4x aa 16x af at 1920 x 1200. i also dont think this card runs crysis at 1920 x 1200 with aa/af at a smooth clip.



downsized from 1920x1200. it drops to high teens low 20s constantly

other games needing a big performance boost include dark messiah, fear, oblivion with any of the mods that improve visual quality. it will be tens of years b4 we dont have to worry about performance.

 

A year or two? My guess would be in less than 6 months. 1920x1200 with features cranked up on new games like Crysis should be quite demanding. It seems to me that with SLI/Crossfire demanding graphics have only filled the void and PC development has reacted in kind. I personally don't forsee the kind of gap we saw with DX9 where games began to exceed the general performance envelope of NV30 and R300. We may have to wait a similar amount of time from API release to games that use it to any serious degree, but with how the PC market has changed with larger stratification of GPUs, higher enthusiest cap and performance, and now SLI I feel games have only come to expect such and are becoming more demanding.

I could be wrong of course because 1 or 2 years is a long time.

[qote]Edit 2: Oh, yeah, this is supposed to be about the R600. Given the nVidia G80, performance really shouldn't be the deciding factor for this generation, because the 8800 GTX I have is more than I'm going to need for some time yet. Image quality should be. But the G80 has such great image quality, that I have no idea how ATI could substantially improve upon it.[/quote]

Personlly (i.e. for me) I would qualify this with a) a lot of us have not decided to buy a DX10 GPU yet because DX10 isn't even in the wild and b) seeing how initial Vista software performs, especially apps that begin to give us some feedback on how some DX10 features perform on each platform and how each does in this regards. I don't see G80 as being such a performance win that I wouldn't wait or consider another GPU. This is my perspective based on owning a number of NV products. It ultimately comes down to when a killer PC app arrives and what is "best" at the time for many (or when they happen to have the funds to upgrade), but after my lone experience with ATI (9700) I don't put out of question one or the other producing an excellent new product with a new API launch--good enough that the other takes a while to catch up, and in return means the part with more performant API support has longer longevity.

I think performance is still in play for a lot of us, but your point on IQ is right to a degree. As much as high IQ is important to many of us, the little amount of "play" HQ AF and MSAA & FP16 got last go around, it makes me wonder. But for serious enthusiests, not just people burning cash, it is hard to beat what G80 gives with IQ. Whether ATI can beat that, I presume that is one of the reasons for a 512bit bus. We will see...

 

It could very well be an attempt at guerilla marketing by some marketing droids at AMD/ATI. Facts do not all have to be true, just packaged impressively. And judging by you all, it seems to work very well.

 

Framerate of my 8800 GTX to 1920 x1080 is of around 20 fps in the outdors with
vegetation and HDR+MSAA 4x in the modern games , like Armed Assault, Oblivion, Call of Juarez….. Perhaps in that point it is where the bus of 512 bits has something to say

 

Well transparency multisampling has a negligable performance hit all around compared to transparency SS. The perf hit is usually 1-3% at a worse case scenerio. Even in Oblivion. Transparency SS looks alot better but TMAA has a very low performance impact. Infact. I never turn it off. The TMAA hit isnt specific to oblivion. But all titles.

Most people dont use it though because in alot of titles transparency SS has such a low impact due to there not being many alpha variants. But using EATM or TMAA in a title like Oblivion is a decent tradeoff because the performance hit is so small.

 

I knew that the R600 review on level505 might be not that rigid... but could you guys please move the talk on 8800GTX score on its thread As I am now starting confuse on reading this thread (I just try to find out how the possibility on whatever that site claime to be valid)...

Sorry for interuption... and a Happy New Year 2007

 

happy new year, make sure u were ur stunna glasses at night

 

Thanks for explaining that.

I was wondering, does EATM still have the screendoor effect? Or was that resolved in the 6.12's (still using 6.11).

 

It's resolved . At least from what i've seen. EATM really has good potential to get a nice feature.

 

They weren't using MSAA thou, they used TSSAA(thier term) and got those results, something aint right.

 

Rainbox Six: Vegas says hello............and Splinter Cell: Double Agent.......and we have yet to see how well it'll hold up at high res against other UE:3 games and let's not forget DX10 games.

Hmmmn. How well does a 8800GTX run Flight Sim X at 1920x1200 with everything cranked up? Oblivion is getting a bit old now.

 

But EATM basically offers similar shimmering curbing attributes as the performance SSAA modes on ATI hardware -- plus a lot of added alpha test detail.

In your opinion how many samples of multi-sampling TA would you feel matches nVidia's SSAA TA -- when it comes to curbing alpha shimmering in worse case color contrasting areas?


Plus the added detail in areas adds more immersion, too.

 

And why having more quality with a performance mode for alphas is paramount in heavy alpha test areas.

 

I'm sorry, I don't have those games, but are those ones you listed even out yet?

As for Flight Sim X, I have a really hard time believing that a flight simulator would have any troubles whatsoever running at high resolutions. Flight Sims are usually more CPU-bound, as there just isn't much overdraw to speak of.

 

I just have to get this crazy idea off my chest: Hard launch Jan 22, no lead time for the press, bundle with Vista.

 

I think Splinter Cell has been for quite a while already, and Vegas for a week or so, too?

 

Well looks like Level505 are still on the job..: Regarding the lack of photos they've got the following comment:
