How well does oblivion scale in SLI?

post #1 of 20
Thread Starter 
My rig is in sig.

I have a unmodded game at the moment. I do hower have Qarls texture pack along with some juicy shaders which are dropping me down between 30 and 40 fps. I havent even put all of my others on yet and i know it will be a strain.

Im looking into another 470 for sli. Second hand they can be had for cheap now.

Does oblivionn scale well in SLI? i need to try get it back up to 60fps solid.

I used to play heavily modded Oblivion a lot. I can't speak for the 470's, but I went from 1 GTX280 to 2 and noticed about a 60% gain in FPS.

Depending on how well your cpu does with it, you can expect nearly double the fps. 55-76ish would be my best guess, assuming again that the cpu don't hold back the gpus. I believe oblivion is dual threaded which is why I say that. I know my i5-2500k at 5Ghz was still the bottleneck for my 470, but I didn't have any shader mods to lower my fps that low.

The texture pack is going to hurt you regardless as you only have 1.25gb of VRAM, it's not so much the graphics card power but the VRAM limitations. You'll definitely get an increase in fps from a second 470, but I doubt it'll be enough to warrant the cost since you're already vram limited. Oblivion with mods gets extremely VRAM intensive.

You sell your 470 and get two of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130611&cm_re=2gb_460-_-14-130-611-_-Product
for $170 each, considering you can probably get $140-$150 for your 470, and you'll most likely see a greater increase in Oblivion framerates, especially minimum framerates, than adding another 470 just from the added VRAM even though the 470s have more raw power than two 460s. Now, other games will do better with the two 470s.

Selling my 470 for 2 of them is pointless. A second card should give me enough vram for oblivion. 2 470s is better than 2 460s.

Plus i cannot afford that route im getting another 470 second hand. Plus its for battlefield 3 and other games in the future not just oblivion.

I have Qarls texture pack with a couple of shaders. The one that is a killer is the depth of field shader i am using which is fantastic. Qarls texture pack is not maxing my VRAM out.

So if your processor was a bottleneck how is my 3.6 core i7 with 2 470s not going to bottleneck with oblivion either?

SLI does not add VRAM. The VRAM on both cards is mirrored. Even if you went to 3x 470s, you would still only be able to use 1.25gb of VRAM. My suggestion of 2 2GB 460s was if you're only concerned with Oblivion and using texture packs (which, judging by the OP, seemed like your primary concern). 2 470s is always going to be better than 2 1GB/768MB 460s, but there will be times that 2 2GB 460s outperform 2 470s, adding texture packs and stuff like depth of field is one of the ways to go towards that situation. Will a second 470 improve your framerates? Absolutely. But, two 470s are still going to have very low minimum framerates when using mods/texture packs due to the lack of VRAM forcing textures to be loaded more frequently.

A second 470 is a good setup, you're just going to see the rewards of it far more in other games than you will in a modded oblivion due to the lack of VRAM vs texture packs.

Well im not doing bad with serious shaders. If adding another 470 along with FCOM and other mods gives me around 50 fps then i would be happy. I have a number of my sliders at 50% along with lower shadows and stuff so im not totally maxed and and i dont need to be really.

As long as i see a gain with another 470 then thats good even if it is 20 fps for oblivion its still closer 60fps which is were i want to be at.

As long as you're willing to do what's necessary to keep vram usage in check (i.e. dropping AA, texture quality, and possibly resolution), adding a 2nd 470 should give you some good scaling in Oblivion ... 70-80% would be my guess.

Im not willing to drop anything lol.

Currently i have the shaders that i want and Qarls texture pack 3.

Im getting between 15 to 20 fps. HBAO and the deph of field shader im using is mega on the fps. You say 70 to 80% how many frames would i be looking at to what i currently have?
