Testing method: FRAPS run through the "Masyaf" level, results are the average of 6 three minute runs
No better candidate exists for closing an article focused on testing DX10 games than Altair and his Creed. Using a proprietary Ubisoft engine, AC comes with a very solid DX10 implementation, one actually faster than the DX9 one ... but get this, it also was the first game to implement DX10.1! We've spoken about this in detail (see our initial Assassin's Creed DX10.1 article and Addendum), and ultimately watched UBi remove the 10.1 pathway for rather foggy reasons - with support unlikely to ever return.
The good part is that you can enjoy the game with DX10.1 as long as you don't install the 1.2 patch, and we recommend you do so without fear. The bad part is that we're going to be politically correct in our work and test the game the way it was meant to be tested, with the latest patch installed. To evaluate 10.1 performance, just add about 20% more performance to the AA numbers on both cards (the 4850 and the 3870 are both 10.1 capable), and you'll be having a right image of things.
Note that we changed the FRAPS run a bit in order to try and shift it towards being more GPU bound (results were not completely satisfactory so we're still working on that), resulting in numbers not directly comparable to the earlier ones.
AA only goes up to 4 samples, and we're controlling both it and AF through the game's configuration file. This is the third game in the DX10 batch that relies on custom resolve. Assassinations ... errr ... frames per second:
As we said earlier, our attempts of shifting the binds towards the GPU were less than successful, so we're not exactly seeing a significant delta between the cards. As has already become boringly predictable, the gap widens with AA and, by looking at the numbers, it's quite obvious that the 4850 is a better choice for this game ... which is a really trivial conclusion since it's always been a better choice throughout this review.
A Closing Teaser
Looking for a conclusion? Sorry, not here ... in a bit we'll be looking at single card performance in DX9 titles, then we'll check out how Crossfire does in DX10 and in DX9. Once we have all of those sample points up, we'll make some final considerations. As usual, however, it's up to you to draw a definitive conclusion.
