Hi all.
I played the Mafia II demo and I really liked it. The thing is I was fiddling with it and found few issues.
First let me tell you the physx effects are quite good, I like them. However I am with ATI card and its "not supported" so it runs horrible with it.
I found a site that explains how to tweak it and after deleting the Cloth directory it works MUCH better.
The problem is following.
I run the included benchmark on Medium Physx and Graphics to MAX.
1st time demo runs I get 40 fps avg
2nd time demo runs I get 32 fps avg
3rd time 40
4th time 32
and this is a pattern.
There is some general bug with it or its done intentionally and I am leaning towards the second guess. Why? Here why
When I run first time all works ok I dont get under 30 fps anywhere on the benchmark. However on the second run, right after we get into the warehouse, it starts to slow, and slow and slow until it runs about half the fps (where it was 30 first benchmark now is 15).
How is that possible? Every time very consistent, one fast run, one slow run.
In game its something similar - I start game everything is going 50+ fps, I shoot the guys from the window, get down, then get into the warehouse, where it still runs ok but with each scene its like its slowing down and slowing donw. Even after fights where nobody is shooting nothing is exploding it still runs slow.
Now I checked and right when I get into the elevetor I get around 20 fps. I go up, leave them to kill me so it reloads it and starts at the elevator again. NOW I GET 50!!!
on the same scene, same elevator. I go up start shooting and it gets dropped quite quickly again.
Its either some memory leak or intentionally done so it wont run on ATI cards
I am not sure though if its physx driver or it could be ATI graphics drivers (although I cant explain how graphics driver prob could explain that)
My guess is some list of objects that have to be calculated is not cleared and when you play and progress its filled with more and more and more objects to calculate and its gradually slowing down.
Other interesting thing is that my cpu dont go over 70%. Its a 3x PhenomII 720
Anyone else can test and post results (with ATI cards and with nVidia cards)
Thanks in advance
