Another option that we originally thought might be possible would be to use the older card as a dedicated PhysX card. Prior to doing anything like this, of course we did some Googling to research whether this was even a good idea. We were greeted with forums upon forums of mixed opinions. Most of the opinions we found did not recommend going out a purchasing a second graphics card to be used as a PhysX card and that the money should be put towards buying an even more high end graphics card.
We also found that other users had said that theoretically this would be beneficial, provided the PhysX card was a higher end card. So of course, we needed to try this. Our research so far has shown us mixed opinions and no definitive answers. Today, we are providing you exclusive data as to this conundrum. Before we get started, we know very well that the likelihood of the second graphics card set to process PhysX alone may not improve graphic performance, but with so many mixed opinions we needed to see the data for ourselves.
It is an advanced platform that game developers can use to add advanced visual effects to their games. To quote Nvidia, physics is important to gamers because:. PhysX is currently enabled in multiple game engines, some you may know such as Unreal Engine 3, Gamebryo, and Unity 3D. Probably one of the most well-known, and somewhat recent, game to use PhysX is Borderlands 2.
For a full list of Nvidia PhysX supported games, take a look here. This takes the physics calculations away from the CPU, which as you can imagine allows the CPU to worry about other important tasks.
Nvidia, at one point, did focus their energy on dedicated physics processing unit on a standalone PhysX card. Dedicated Physx Card. Forums Hardware Graphics Cards. JavaScript is disabled.

So i have a classified as my main card, and was going to use my classified as a dedicated physx card. However, ive seen people say its not worth doing so anymore, but they dont say why.
I would have the in a 16 slot, and the in an 8 slot. Jun 20, 21, 8 85, 4, It's still hard to justify keeping the card in the case IMO. Gregg Eshelman Reputable. Mar 25, 46 0 4, 1. First off you either have to use old drivers or hack the newer ones. Second, it will only work with specific games that can use a card separate from the main GPU for PhysX. So if the PhysX capability integrated into your main GPU is better than in the secondary card you want to use for PhysX, there's no point to doing it.
The only reason you'd want to do this is if your main GPU doesn't have PhysX, in which case it has to be a pretty old nVidia card and would be worse than your Are you sure about that? I doubt it. Yup, hack the drivers. Watch the video. Using a separate GPU for PhysX is disabled, I assume mainly to keep people from using those old and now pitifully wimpy standalone PhysX cards, which will slow things down. And is it worth waiting for them, especially the lower end ones?
Question Changing from integrated graphics to a dedicated graphics card? Question Dual monitor with dedicated and integrated graphics doesn't work. Ignoring the doubled cost of SLI, it's also going to suck down more power and generally you don't get the performance gain compared to investing twice as much money into a single card. I have the other cards already wont be purchasing them especially for physx and the PSU is a watt corsair that is fairly new so I have the grunt there.
You can just dedicate a GPU to process only physics in the graphics card options if you have multiple cards. You'd be better off getting a second graphics card. The CPU does a great job of acting at the physx device. And we'll assume that you have a W PSU to handle the entire system under load. Here are the benchmarks from Anandtech, and while they aren't perfect they should be a good baseline.
If you really want to push the limit then SLI is for you, but if that's your game why not just invest in multiples of the top card out there? At the end of the day, do what you want, but SLI really doesn't make practical sense unless you just so happen to have modern cards sitting around for some reason or another. Can't say much for others, but I have run into cases where people do Crossfire dunno if it works with SLI after upgrading.
If you have an R7 and upgrade to an R So I completely agree with you. However, if I were to upgrade and had the spare card still? Heck yeah I would keep it in there. Which is what I said in my first post. In these cases, your card is wasted. Why is this? Because PhysX is different from physics. Physics is just a term used to describe a generic in-game engine for Physics. PhysX however is it's own special engine! A good deal of games have adopted it, but not all. Unfortunately my knowledge of SLI compatibility is slim, so I don't really know if they are in fact compatible.
My recent cards have been ATI and the rule there was "same series" are compatible. A quick google seems to indicate that in fact the cards shown are NOT compatible. However for the added power consumption, I don't see where this is worth it. Benchmarks show only small increases and only in games that support PhysX. Doesn't make much sense to me all in all. SLI works just like Crossfire, the two graphics cards must be identical to operate in that manner for both each brand's version of the same thing really, which is GPU teaming that is typically but not always necessarily via hardware bridge.
Crossfire Compatibility Guide lists your options for Crossfire there are a few ATI cards that are literally the exact same unit with slight variations in shader cores, core clocks, and on-board memory but are the exact same GPU so they are compatible to mix. The long and short, is if you want to get the goodness out of PhysX, easily the best choice for performance is a dedicated GPU for PhysX as it's own unit, and worry about your primary graphical processing as a separate function entirely.
