The Framerate Analysis Thread part 2

Last edited by a moderator:
I played the PS3 ver of Lost Planet 2 MP demo & ... the tearing is unlike RE5 xbox 360 where it occurred mostly on the top half, here it can happen in the middle of the screen.
The biggest disappointment is the framerate, I doubt if its even 30FPS for the most part.

Isn't the hit for triple buffering at 720p only ~3.5MB or so when you're rendering with no msaa? Considering their engine already supports a well implemented form of triple buffering on the PS3 surely giving it up is just a flat out poor decision? Is that extra few MBs of RAM really going to make all that much difference to the texture quality?

They probably were thinking about response & lag for MP, but who knows. Typically you don't see that particular setting different between MP & SP.
 
That's the largest difference I've seen in performance in recent times. So despite jumping to version 2.0 of the engine, it seems that it still works better on the 360.

Look like 360 version got better since last year's demo, while the PS3 one got worse. Granted, this is a multiplayer demo but still, I was hoping for parity. Last year's demos were far more comparable.

The uncapped framerate in PS3 code doesn't helps with tearing numbers either.
It also made the control feel sluggish with jumps into < 30FPS when there's a simple scene followed by a drop to 26-ish FPS as soon as you look towards a complex scene.

Yes, just like all of Capcom's PS3 MT framework games.

If by TB you mean triple buffering then no, but the tearing was nowhere as noticeable. The uncapped frame rate actually wasn't bad in single player mode either.

I think the first LP was capped initially then patched to remove that cap, and it wasn't that bad afterward. Though the controls weren't that smooth compared to the 360 version regardless, so it could've been another coding issue.

I'd recommend testing in the City areas as these put by far the biggest strain on the engine in the PC version, at least.

Well both DMC4 and RE5 were triple buffered on the PS3, I was sure the previous PS3 demo of LP2 was but I may be mistaken, just going from memory.

Edit: Just checked, yeah you're right, the previous demo was the same.
