I can't use PhysX in games like Metro Redux and others with an AMD R9 270X gpu?

lol, buying a new GPU just for some dinky PhysX effects that are only used in a handful of games.

Physx is pretty minor and unimportant, I wouldn't bother with it. You can go on Youtube and watch videos of what it does and see if it's worth paying double or triple the cost of your GPU to get an Nvidia one for

I guess I will have to get a nVidia card soon.
What's the best one I get for under $200 that compares to a the R9 270X that I have now?


None comes remotely close in that price range

Yes I know it's in the options to select, but it drops the fps a lot. I can get 60fps, but with PhysX on it drops down to low 20fps.
And my PC is pretty good for gaming... ntel i7-2600K 3.4GHz, Intel H67 Mobo, Sapphire R9 270X 4GB, Rosewill 550W PSU, 8GB 1333mhz RAM, 2TB HDD, Win7 64bit Home Premium.

That's because it runs off of your CPU like already mentioned a few times.

It really isn't anything amazing tbh, I used to use it all of the time, but I switched to a 290 and don't miss it one bit. The price performance ratio of the 290 when i bought it was too good to pass up.

Can you still use a dedicated Physx card with AMD cards? Or could you never do that.


Not anymore.


One of the reasons I hate Nvidia. It's one thing to keep their tech to themselves, but in this case they're hindering an actual Nvidia card from using it


It's also hurting a potential revenue stream with people buying mid-range/low-end PhysX cards.
