Another dedicated PhysX thread

[alexisvx]

Hi all,

I have read quite a few threads on this but I thought I'd ask again as my questions are slightly different and some of the benchmarking tests done are for older cards. 

 

I own both the GTX970 and GTX650Ti Boost (2GB). Is it worth using the 650 as a dedicated PhysX card? I have read both that it does create a significant boost for PhysX enabled games but also that the 970 is enough to handle modern PhysX games. So my first questions is, does it make a significant difference for modern games (the ones that use PhysX) and games to be introduced in the near future?

 

My second questions is how do I benchmark myself to a) make sure that adding the card won't worsen my performance and b) to properly test performance change? My understanding is that to test the PhysX I should run the GeForce PLA. But are there any other tests I need to make to test overall performance like 3DMark/Unigine, should I also test the CPU as I have read that using an additional card uses one of the cores?

Also do I need to test on actual games? I own all Batman games expect A.Knight. I would rather not test on games as I would need to download them. I only have Witcher 3 and Far Cry4 installed at the moment.    

 

In summary my questions are: 

1. Does using the 650Ti boost as dedicated PhysX with the 970 give a significant improvement for PhysX enabled games?

2. What benchmarking tests should I make to see overall performance change? 

 

 

Thank you!

For the most part no, but since you have both cards you could try and compare results.

test with arkham origins this game has a lot of advanced physX calculations, then and see if it improves anything and if it even work...i think the 970 is powerful enough to handle advanced physX in games without noticeable impact on performance but i might be wrong...please report your result as i'm curious to know

there is an integrated benchmark in that game...run with maximum graphics and do a couple runs for each

Would you suggest that I only test with Arkham Origins? How about finding out if it bottlenecks other areas? What should I use to test the whole system?

I did a test and here are the results:

Summary: Not a significant increase in performance

Details:
2 tests PLA Game benchmark and Batman Arkham Origins benchmark
All settings at maximum

PLA:
GTX 970 on its own: Max: 62.4 - Avg: 60
GTX 970 +970 TiBoost: Max: 60 - Avg: 62.8

Batman:
GTX 970 on its own: Min: 38 - Max: 65 - Avg: 47
GTX 970 +970 TiBoost: Min: 46 - Max: 74 - Avg: 56

I would call the increase in frames in batman significant.

 

Deffo worth keeping experimenting with, for sure.

Looks like a 10-15% difference in performance on the Batman game. Pretty nice boost, i would say. Though, at the end of the day, it depends on if you want to use the extra power (even if its only a 650) and produce a little extra noise (don't know if your card is loud or not) to be worth it. I would say, if you are in a pinch, and need the boost in a PhysX title, then go for it.
