For people that are curious about the performance...
I have a GTX970 Gaming overclocked to 1500mhz, Intel 2600k overclocked to 4.9GhZ and 8GBs of RAM @ 1866mhz. I game @ 1200p (1920x1200)
All settings maxed out, except AntiAlias. Seems that TXAA and MSAA kill the sh*t out of the performance.. which is understandable but not on a card that is faster then the stock GTX980. Which is a goddamn flagship GPU + this game is nVidia Gameworks optimized. (YEA RIGHT).
With FXAA i got around 70 fps average. Drops to mid 60's and to 50's in cutscenes where there is Depth of Field...
Really wierd. Godammit Ubisoft...iam sick of their shi*ty ports (Watch_Dogs), i hope they fix this stuff with Day1 patch because this game looks really promissing.
THEN iam going to buy the game. Not making the same mistake as i did with Watch_Dogs.
As for the save games...i can confirm, upon leaving the game progress disappears, i guess we will have to wait for a proper crack.
And here's a youtube video that i just uploaded for you guys to see, sadly no Shadowplay counter in the video, but the lowest the frames got was to 55fps when Arno (the kid) ran into the guy with the food in the cutscene. (part where the guys behind him are smuged with bokeh depth of field), and 63 frames in the courtyard just before the video ends. ( at the moment just 1080p, after processing it will be available in 1080p60fps) Hope this helps you guys, good luck.
