I just did a couple of custom AC Unity benchmarks (1.30 patch) and recorded them with my camera.
I cried!
(if you decide to watch the videos be warned that I use some sexy nsfw wallpapers)
ASSASSIN'S CREED UNITY 1920X1080 CUSTOM ULTRA RADEON 7950 @1.1Ghz CORE i5 2500 @4.8Ghz
ASSASSIN'S CREED UNITY CUSTOM 1920X1080 GTX 570 @850Mhz CORE i7 860 @3.9GHz
ASSASSIN'S CREED UNITY CUSTOM 1920X1080 GTX 570 SLI @850Mhz CORE i7 860 @3.9
7950, environment quality ultra, textures ultra, shadows high, ambient occlusion SSAO, FXAA, 36.5 fps
GTX 570, environment quality v.high, textures low, shadows high, ambient occlusion SSAO, no AA, 19.0 fps
GTX 570 SLI, environment quality v.high, textures low, shadows high, ambient occlusion SSAO, no AA, 16.0 fps
I was not so disheartened by the 7950 result, as I was with my 570s.
Even using lower setting did not help. There's a huge video ram bottleneck. SLI only made things worse, due to the extra data needed.
I mean I have run other vram demanding games on the limited 570 framebuffer, but with the help of the rest of the system (big ram, fast buses) it kind of alleviate it.
For example:
WOLFENSTEIN NEW ORDER CUSTOM ULTRA 1920X1080 GTX 570 @850Mhz CORE i7 860 @3.9Ghz
BATTLEFIELD 4 CUSTOM ULTRA 1920X1080 GTX 570 @850Mhz CORE i7 860 @3.9GHz
BATTLEFIELD 4 CUSTOM ULTRA 1920X1080 GTX 570 SLI @850Mhz CORE i7 860 @3.9GHz
THE EVIL WITHIN 1920X1080 MAXED GTX 570 @850Mhz CORE i7 860 @3.9GHz
It run those quite nicely with framebuffer at maximum, like the Far Cry 4 benchmarks I posted on its thread. ACU won though!
PS I am not even going to try to start it on my 5850s lol.
