Is a dedicated PhysX card worth it?

[joetotheroy]

I just wanted to ask if I should get the GTX 750 Ti as a dedicated PhysX card for a GTX 770 4GB. I will mainly be playing PhysX games, like Planetside 2, Borderlands 2, and Assassin's Creed 4. Will the GTX 750 Ti be worthwhile?

 

[ingtar33]

give it a try. Looks sorta pointless to me. that 770 will hit 60fps in all 3 of those games with or without help.

I have 120hz monitor, and I want to hit the limit on it. Will running the PhysX on the 750 Ti increase my framerate?

Yes. Assassins Creed 4 will drop to 20 FPS with gtx 770 all settings maxed when you use PhysX. For many games right now. the GTX 770 can handle PhysX. But it may need the boost for future titles that will incorporate it like Watch Dogs, Dying Light, The Division, etc. I'd recommend a 750 ti as a PhysX Dedicated card.

ever consider getting a second 770 instead? 😀 . not only you can get much better performance such setup also able to handle gpu accelerated PhysX with ease....except PhysX in AC4 maybe. AC4 is nvidia very first attempt to put PhysX APEX on top of other physics engine (AC4 use Havok. The upcoming Watch Dog will also use Havok but i haven't heard the game will use GPU PhysX). i think that alone contributing the massive performance hit when enabling gpu PhysX in AC4. in games that have native PhysX support like UE3 the impact of gpu PhysX is so much even less with mid range gpu as long as the cpu is not bottlenecking the gpu.

my previous setup (2500K +GTX460 without dedicated gpu physx car) i was able to play Batmat Arkham Asylum with gpu PhysX set to high and still able to maintain 60FPS in most situation. the only time my 460 have to struggle is in any level with Scarecrow 'world' level.

If I could afford two GTX 770s, then I'd rather just go with a GTX 780 Ti.

The 750 Ti should give you a pretty large boost to your fps. At the very least it will prevent massive drops in fps.

well you don't have to get two 770 in a go. but i take it that you not a fan of SLI system

Yes, mainly because I don't want to run into optimization problems.

the tech is quite mature actually. for most triple A games nvidia able to bring in SLI support on launch day and for the titles that they have heavy involvement with (TWIMTBP) SLI profile will be available in drivers for months ahead of game actual release. the only problem with multi gpu tech was it's heavy dependency on drivers.

idk if anyone mentioned this but assasins creed 4 is capped out at 62 fps

The 750 ti will absolutely help. I have one with my 780 ti, and it's great in PhysX titles, and the 750 ti does a really good job! I'll share something I wrote for someone else who asked me a similar question. It's copied between the lines below. The short of it is that the little 750 ti card gives a surprisingly solid boost to even a powerful graphics setup, at least in PhysX apps. Love!

Here are two useful articles about the latest information on dedicated PhysX cards (if you haven't already read them). The first one is called "How much difference does a dedicated PhysX card make?" It shows that, in PhysX titles, a gtx 650 handles PhysX as a dedicated card better than two Titans in SLI.

The second article is called "Using Maxwell's GTX 750 Ti as a dedicated PhysX card." It shows that the 750 ti is actually a little bit better than the 650 and 650 ti were. As a PhysX card, a 750 ti will last you MUCH longer than it would as a primary card, though it's not the worst primary card.

As a disclosure, keep in mind that not everything uses Nvidia's proprietary PhysX, but for things that do, having a dedicated card is really nice. A 750 ti currently offloads PhysX for my 780 ti, and it really makes a big difference in PhysX titles. Here is a link to my personal benchmark results using Nvidia's PhysX benchmark.

780 ti only - 79.3 (average) 104.6 (max)
W/ 750 ti - 122.1 (average) 218.5 (max)

To be fair, that bench was the biggest improvement, and games weren't as much of a jump, but they still showed significant improvement. The best thing is that it prevents little hickups and major frame drops. 😀
