AMD/Nvidia Together

Potentially stupid question time!

I found a pretty old machine in my house and it has a 9800 GTX in it. Would it be possible to put this in my rig (in sig) and have it running just for the PhysX features and have the 280X dealing with everything else?

interested also, going home today to install my new 290 tri x, ive got a 460 in there in a moment, id like to hack it to use the 460 as a physx

An nVidia GPU will work alongside some of the older PhysX titles but from what I am told, the newer titles have locked out PhysX if an AMD card is in the machine.

Search for Hybrid Physx. As Gregster said, it won't work with newer titles such as Arkham Origins or Assassin's Creed IV.

It can be done but takes some tinkering with a mod and drivers.

What games are you planning to play? I've found physx doesn't really add that much.

Not much now if it doesn't allow you to use it in modern games.

Just found the old card and thought it might be an option.

I really wanted PhysX on Borderlands 2, but I'm running a HD7970. Is the tinkering all that difficult or is it not really worth it just to get PhysX...

That's one of the games I want to try it on as well.

A decent cpu can actually handle the PhysX on Borderlands 2. You might have to manually change the setting in WillowEngine.ini to turn it on though.

What setting do you have to change?

Yeah set to low it works quite well. Frame rate will drop now and then.

Doesn't handle it all that well when you up the PhysX setting though. After all it has been coded to be ran hardware accelerated.

Tried it when I had a couple of 7950s (with my i7 3770k @ 4.5). Wasn't playable on the higher PhysX settings when you actually had them drawing.

Played ok for me, sure fps dropped at times but I still finished it with PhysX on high.

Dont think I ever dropped below 40fps.

Here someone with an i5

Again with shooting, enemies.

Yeah, I wouldn't personally put it higher than medium.

PhysXLevel=*

Replace the star with 0 for low, 1 for medium, or 2 for high.

Old PhysX hack works up to PhysX 2.0+ titles on older Nvidia drivers, no hacks work for PhysX 3.0+ without serious grief with possible OS damage if you can get PhysX 3.0+ hybrid working-some can get it running setup dependant.

Ah nice one, thanks very much. I'll get that changed when I get in from work tonight

At low settings and with some hefty frame rate drops maybe but its not a very good experience at all.

@DJ Bucho- It is one of the better examples of Physx and for me makes the game look a lot better. I played it with 7970 crossfire and with 780 SLI and preferred the latter as the eye candy is a lot nicer. Lots of nice effects on liquids and sparks/explosions

Superpatsy · 17 Jul 2014 at 18:52

Just been playing Borderlands 2 with PhysX set to high and I had absolutely no issues at all apart from the odd frame-drop.

I enjoyed it, so you be wrong
