Dedicated PhysX card for 760?

[Guest]

Hello,

 

Recently, I've noticed my new PNY GTX 760 has been absolutely murdered by any game with PhysX enabled (any 3 Batman titles in particular)- on 2009's Asylum, turning it to 'normal' drops the frame-rate to 25FPS! What's up? Also, even my little brother's Lego Marvel game runs choppy! It's a Lego game! Tomb Raider gets better FPS than that (although I would assume it's just bad PC optimization). So, my main questions are;

 

-What would cause it? My CPU is only a C2D, but I thought the point of PhysX was to use only the GPU

-Is it even worth trying my old OC 9600GT as a dedicated card, or is that worse/should the 760 should be able to handle it itself?

-Also, Arkham Origins ran 30+ FPS with everything fully maxed, but recently, even having PhysX on 'normal' makes it drop miserably. Nothing else changed in my system- not Steam, not my drivers, nothing. And I run a tight ship when it comes to what uses resources on my PC- during gaming, its Steam and nothing else.

 

Thanks, any help is greatly appreciated!

Have you even checked that the 760 is the default PhysX device?

The 760 should be fine running PhysX on it's own. Try using stable drivers instead of the beta ones.

Make sure PhysX is running on the 760 and not your CPU. Even considered, that Core 2 Duo is definitely holding you back. The batman games run flawlessly with PhysX turned on on my GTX 660 Ti @2560x1440 (rest of specs in my sig)

Buying a dedicated card doesn't make sense, using a old card do.

Unless you already have 3 cards and doing it for giggles.

 

And it's probably cause by the CPU as I run Batman AC perfectly everything maxed out on a GTX570. (But at 1280*1024)

uh bottleneck and a half that core 2 duo will be the problem most likely

Invest in a better CPU and more Ram, the come back to us.

Yeah, it's on the GPU alright.

The fact remains, you have a lot of wasted potential in the 760 by pairing it with a Core 2 Duo. That's like me pairing my Geforce 6800 GT with my i5 3570K. I wouldn't even worry about thinking of a dedicated PhysX card until you upgrade your CPU/Mobo/RAM.

Yeah, I'm building a new PC soon (sans GPU), so I guess I'll just live with it until then .

You are only getting around 30% out of your 760 pairing it with an core2duo, buy cpu standard is prehistoric now  

 

Still a great chip for a none new game gaming PC though, paired up with an appropriate gfx card.
