| mantlepiecek said: Fable 3 already had frame-rate problems when I played it. You really think MLAA is going to help it in such a situation? Either way I am not holding my breath for the 360 to show MLAA. Even if its possible its going to take the GPU strength which will be more valuable as time goes on. Good news is they managed to get it working at 720p. I wonder why they never used MLAA at 3.7 ms though. Its the same as the PS3 MLAA, could have easily used it in games like DA 2. |
The difference is that the PS3 MLAA, offloaded to the Cell SPUs, works in parallel to the GPU, whereas these are GPU times.
At 30fps the GPU has a 33ms time budget per frame. Adding 3.7ms means adding an 11% cost of the total time budget. That's not so little a cost when an engine is already running tight: if that increases cost sends -say- 20% of the frame-rendering over the 33ms threshold you get something like a 24fps, that is a quite noticeable framerate stutter.
Now if they managed to reduce it to 1.3ms with some consistence, that's a much better result of about 4% of the rendering time budget. Unless the engine is already squeezing the GPU times very tightly, it will lead to a much more stable framerate.
