PhysX on ATI HD 5770 (Mafia 2) HD

I have surprised I could enable PhysX with an ATI card, but I soon relized the things aren't going at the way I want...

can i damage my (ati) video card if i use physx? it is required for a couple of games i have, but i dont know if i should install it.

[macskap]

@AALLJJNNDDRR No u can't.

@macskap how is it possible that i get only 8 fps with these settings:

Radeon HD 5770 1 Gb

Amd athlon x4 640

4GB DDR3

windows 7 home preminum.Everything maxed and physx ON.

[macskap]

@seppoonmelkonen Cause u have enabled physx and u have ATI card...

[wodka450]

@macskap i've seen a few videos featuring ati cards running physx decently around 20 fps on average...

[macskap]

@wodka450 Maybe it depends on ur memory. I had got less and less FPS while I was playing more and more. So if I destroy something, the information of the pieces of the destroyed object (thats physx) will be stored in the memory. And if u have small memory, it will be full soon. I had ordered 2X2 Gigs of 1600Mhz DDR3 RAM, now I have 2 GB 1333Mhz, so Im gonna look after this shit. :)

Hope it was understandable, Im not an english pro.

This was my first comment of the year :)

Happy New Year! :)

@macskap im sorry to tell you this but physx only works with nvidia. when you turn it on without nvidia, it uses your cpu.... duh

[FFF693]

Not really!!

[zixian96]

i've have crossfired 6950 with 8GB memory and 15 2500k @4.5ghz but...

i only get 23 average fps in the mafia II benchmark with physX

[filippo333]

I don't see any difference other than the lag in the Physx version :|

[SintagmaNominal007]

Which is the difference? i dont know!

@k00LGuY671

PhysX is just a physics enigine first and foremost. Usually it makes all its calculation on the CPU, but it also offers the ability to use the GPU if you have a nVidia card that supports CUDA.

So if you have an ATi card Mafia will do all it's PhysX Calulations on the CPU and since the Apex calculations need far to much computing time they will be omitted completely. You will only get them with GPU PhysX.

[k00LGuY671]

that Apex Physix settings will run on nvidia gpu but on ati it will not, rather it will be a software emulation and will use the cpu as the physix emulator. If I am not mistaken.

A solution for ATI card users:

guyz just do some steps to run mafia 2 with physx ....

1.go to game/edit/apex

2.delete cloths (this will turn off the effects of cloths)

3.delete Assets (optional)

Result: you will have fun running physx only in firing nd explosion without any lag.............(for Ati card users only)

sorry for poor english
