Dedicated physx card

[DraconicFire98]

So, i found out that the best thing to do is setup a dedicated physx card when it comes to borderlands 2 and whatnot, so i'm trying this out....

How does one go by at doing this?

 

One major note though is that I only have one pcie x16 slot and multiple x1... So am I still able to use this method?

 

Hardware that I plan on using are an AsRock h97 Anniversary, GTX 980 Ti STRIX(main card) and an EVGA 750 Ti(physx card)

I currently don't plan on buying any new hardware unless it's absolutely required

 

Also, if it comes to chipping off a piece of one of my pcie slots, then so be it. i'll just have to be extremely careful

No point, you will probs see decrease performance as the 750ti won't keep up with 980ti. I have tired this, and it reduce my fps and cause some instability.

I've heard of many people using a lower end card just for physx, not SLI.. i don't even have a SLI bridge, and my 750 ti doesn't have the slot-thing for it

borderlands 2 runs at ~35fps when I try to use physx... For the games that do support it, i'd rather have a safeguard

[UndueHatred]

I guess. The 980ti should crush that game. I could max it on a 970. Also, only having one x16 slot makes it impossible for you.

Borderlands 2 is a game that can run on craptops. How are you not getting 100+ fps with a 980 ti?

[UndueHatred]

I guess that depends on your resolution and maybe your processor.

physx. I prefer to have it on high, but if I have to, i'll tone it down

 

I might also have a cpu bottleneck... i5-4460, gonna upgrade to a 4790k soon

Just set your AA on off. Problem most likely solved.

what is it with games and having broken, laggy AA? skyrim also has this issue

[UndueHatred]

AA requires increased processing. Just about every single game has frames lowered for AA being on. Most high end bench marks are AA off and on high resolutions like 4K or even 1440p, AA becomes decreasingly necessary for a crisp, smooth image.

[DraconicFire98]

I've got 1080p, and the only AA option I see is FXAA, isn't that generally supposed to be the fastest AA option?

[UndueHatred]

Yeah except, switching it off should boost your frame rate. Then Ambient Occlusion.

[DraconicFire98]

It appears turning off FXAA has boosted it enough to be playable, it's keeping above 75fps, If it gets lower i'll see what turning off ambient occlusion does

Just read this whole post.... no good reason for any of what is happening to be happening so far as I'm aware. What speed is your GPU running at? You should be getting a lot more performance out of a 980ti on 1080p. and you should not see that huge of a performance boost from disabling FXAA. I would double check your in game settings or GPU settings to determine that you are for sure running 1080p

I'm sure i'm running at 1080p, everything is maxed out/on except for fxaa and my GPU is running at factory settings,

unfortunately I do not have B2 to throw my 980ti against it... You should get some HW software to check that your GPU IS actually running at your factory settings. sometimes you can get wack shit on your computer that can affect its speed.

I fresh installed windows 10 the other day, i doubt that anything would have messed with it... I'll get GPU-Z and check if anything seems odd

It just seems that the AA and AO are heavy draws on this particular game. It gave my 970 a hard time, hovering at 50fps until I turned off those settings. Runs fine on the 1070. I would still check your CPU and GPU utilization during the game.

Already did a check the other day, I hover around 70-80%. i'm sure I have a bottleneck in that area

now a high tier card as primary paired with a budget card might not see much improvement ...

 

but what if i have a 750 Ti as my main card and add a non-ti 750 for physx ? would that be of any help ? or maybe I can repurpose a faulty 660 (no video output in 3D aplications) wich has more cuda cores than the 750

 

might also point out that my board has one 16x slot and another slot the same length but with only 4 lanes connected - but that should not matter

[UndueHatred]

Had the price been "free" and the cards are comparable. Sure, stick one inside the machine. Looking at that Linus video I posted... The results were that having one could boost your frames slightly, provided that, again, the cards are similar. Really, though, 5 frames? That was a A 1080, a 1080. and a third 1080 for the PhysX card. PhysX cards are a gimmick and a dumb idea.

[DraconicFire98]

Turned off ambient occlusion and borderlands 2 still drops to the 30s when there's any sort of gunfight

[smokefest]

Useless.

Many videos on youtube about this, deidcated card for physx = useless and most of the time decreases fps.
