I will say though, again, as I have in the past it really depends on the games you play. Many of the triple A games like farcry,batman, bioshock and shadow of mordor...etc. etc. all use nvidia phsix and other nvidia only things, so if that is important to YOU, as it was for me, then Nvidia is a no brainer.
Is there a way to unlock them for AMD card?
PhysX runs fine on the CPU with an AMD card. It is slower than having it in hardware, but it's still fast enough to keep the framerates up. I remember when the last Batman game came out, and AMD players had no problem with all the PhysX code that was in that. And I am not talking about the one that came out a couple of months ago that ran horribly on all video cards from all companies.
i see there is a lot of misinformation when it comes to PhysX. some take it as graphic effect that only usable with the presence of nvidia gpu while in fact PhysX is a complete Physic engine solution like havok was. and there are people that assuming Havok as the only Physic engine exist for game engine. in their view when nvidia gpu not present the game will revert to havok to process in game physic calculation :lol:
also there is this misconception that when nvidia gpu not available all the physx effect will be done on cpu. this actually not the case in all games that featuring gpu accelerated PhysX
except Borderlands 2. go play Arkham Asylum and Arkham City using both nvidia and AMD gpu. gpu accelerated stuff can't be activated with AMD gpu AT ALL. now PhysX also part of Gameworks. so while stuff like HBAO+ can be run on AMD GPU stuff like GPU accelerated PhysX still exclusive to nvidia gpu.
good thing is UE4 comes with PhysX 3 by default.
