I've only just tried this test and so far, I'm quite impressed with this benchmark and if any indications are to go by, it runs just as well or even better than the first Lost Planet, which I have for the PC (Colonies Edition).
My system is a Q6600 at 3.20Ghz, 8GB DDR2 RAM, GTX280 (Stock clocks, ForceWare 191.07 drivers) and results for the DirectX 9 test at 1920x1200, all High settings, 2xAA and V-Sync On, I get an average of 43fps on Test A and 40fps on Test B.
No surprise that the Lost Planet games aren't as smooth (i.e. 60+fps) as Devil May Cry 4, Street Fighter IV and Resident Evil 5, since it is pretty taxing on the engine they run on. Though I would also love to see how Dead Rising 2 PC version compares as well.
Anyways, I would liked to get this game, but like the first and knowing Capcom, I'd rather wait a while to see if this sequal gets it's own "Colonies Edition" instead.
