Hm. A 4.2GHz Haswell should match a 4.6GHz Sandy Bridge, right? If so, the only points to consider are your GPU clocks and RAM
It's definately not the GPU clocks.
My current GPU clocks are VERY conservative at 950mhz / 1375mhz.
I quit trying to push them so hard awhile ago to keep the voltage and temps low and have them both flashed to those speeds on bios 2.
I just tested with vsync off and it runs around 34fps - 52fps (mostly in the 40's)
I'm running Win 7 Ultimate 64bit
CAT 14.6 drivers
And I have a set virtual mem size on my SSD of 200min - 1024max
Doing some quick monitoring using MSI Afterburner, it reports around..
2.4gb Vram usage
4.5gb of system memory usage
and around 7gb pagefile usage despite my system settings
I cannot think of any more info that may be helpful.
So like most people, I have no clue what's different from one system to the next.
I do know people report that system memory usage keeps going up the longer you play.
And I only tested with Afterburner for like 10min running through heavy traffic intersections in the city in a fast car to check the system memory usage.
So take those memory numbers with a grain of salt.
I mean they are accurate for my testing, but may increase the longer its played.
I don't usually use MSI Afterburner , I use Radeon Pro which doesn't report my system memory usage in the OSD.
So I never monitored system memory usage during a longer actual gaming session since i just have FPS and GPU info onscreen with Radeon Pro.
At least it's known there is a patch coming.
Ubi themselves pretty much said the game was only optimized for the consoles unified memory and the pc version currently is just making up for lack of unified memory with GPU vram until they patch it.
So it was never really optimized for the pc platform at launch and was left to be patched later.
Whether that is what he meant to say or not...that is basically what
was said IMO.
