PhysX for ATI - Page 3

Are you sure its not CPU related? it could be your CPU trottling down or anything similar, like I said before, the game runs well even on my laptop with a hd 4650, it has some stuttering but its due to the 2ghz Athlon CPU and all the Harddrive reading.

yea i had some weird questions about cpu and the thoughts that it isnt using all the speed that it could. but i dont know i uninstalled it already because i finished it, the game i mean. i don't know what the problem is only that when the spider boss battle when i destroyed it..you cant imagine the lag..i dont know if i got like 5 fps those 5 seconds of destruction.
amd and Intel dont mix i guess in neither way.

maybe the harddrive is the problem? mine is laptop base so it has only 5400 RPM you think this is the cause of all the problems?

a hard drive wouldnt slow down the destruction of a boss (that would be the stupidest thing for a dev to do)

well if it's a laptop, could it be that it got hot & throttled down?

The spider boss, when ever I destroyed something of his was a lag fest for me as well. My frame rate pummels down at many other levels as well.

How many people with amd gpus are playing this game smoothly ?

you're on a core i3?

how many people have a fast OC'd cpu? plus how many similar systems can compare both nv & ati on the same level?

& if someone 'acquired' the game, how would they know that there isnt a problem with that version (happened before to mw3 & other games)

no my laptop gets hot but never to such level that it would slow down or shut down i have extra cooling so i doubt this is the problem. my CPU should have handle it but then again intel and amd dont mix i quess next time is geforce nevem again ATI..sad

Yes I have a core i3 same as the specs I posted in my profile. The game is running fine on many people's dual cores with nv gpus so its in no way cpu intensive.

This is clearly a problem with amd drivers/gpus.

ya, it's quite possible for it to just be unoptimized... on either the driver or the dev's end

if you look at shift1 when it launched, it just would not run normally on ati until the game patch fixed almost everything & then a driver update did a smaller boost

games<->drivers = handshake, it's rarely as simple as blaming only the drivers or only the game

ATI and Intel mix fine.

Check your Power Options (right click on desktop>Personalization>Screen Saver>Change Power settings). Set to High Performance. You can also change plan settings, go to advanced power options and set Processor Power Management to 100% for Maximum and Minimum power.

You can also adjust settings in your BIOS by hitting Delete key (sometimes F2 key instead) as your laptop boots. In your BIOS probably under Power Management or perhaps Advanced Settings there maybe some settings for CPU management where you can turn off some throttling heat management settings, though most latops have pretty limited BIOS settings which only leaves you with the options available in Windows power management.

If you do find settings that manage your CPU in BIOS you can look them up on the web to find what they do. Don't forget to save your BIOS settings if you alter them and don't worry about other settings because they are very limited for laptop BIOS.

You may also disable Antivirus and other programs while gaming to free up CPU resources. You could also create a custom power plan in the Power Options that you can switch to before gaming. If you do create a custom power plan you would want to set GPU and CPU Minimum and Maximum to 100% and then run a game to see if your laptop handles the heat and continues to run OK. If there are any fan settings you could set them to run fast to improve cooling if the extra noise doesn't bother you too much.

Don't forget to change the Power Plan back to Balanced or Power Saver if you are going to use the laptop unplugged from power or High Performance will drain your battery in probably less than half an hour.

dont worry i already did all that and plans of performance to maximum. im just wondering if i alter heat settings it will go higher thus reducing performance? an also can fans and too much usage od "higher" options cause my laptop to eventually run very slows or somehow damage it?

well i ques i will have to suffer through PhysX related games because all other run just well. but i will keep searching if i fins something somewhere to boost power, beacuse i still dont think the CPU is using all the power it could on some games.

IIRC Binary Domain doesn't even use PhysX.

Backing to Reality

AMD/ATI cards have bottlenecks at higher stages of tessellation due to its current implementation, having PhyX will just bump up a HUGE performance hit (even if it was possible).

More over PhyX even slows down games on Nvidia cards, I really don't find any reason to have it on AMD/ATI too.

None of that should affect Binary Domain though, as that is a DX9 game that doesn’t use PhysX.

If you were meaning in general, then PhysX 2.x is unoptimised no matter what you run it on, but 3.x should be better
Tessellation though is only “bottlenecked” on older AMD cards, the 7k cards are as good, if not a little better than Nvidia when it comes to tessellation in it’s existing implementation.

it's simple, not all games run the same

-binary domain might just be not so optimized for ati rendering (like shift1 on launch, or maybe lost planet 2), this is not necessarily a driver problem
-we need powerful desktop cpu people to blow up that boss to see what happens to the fps, on both ati & nv cards
-the very few games that contain gpu physx, well they usually have an option to turn that off, you shouldnt be enabling it (mirrors edge, batman without mods, mafia2 without mods)
