Sorry if this has already been asked (seems like a pretty common concern) but I couldn't find a thread on it. Is SLI support going to be added at any point? -ArmaAK
I know it doesn't support it natively, but I read it doesn't really act up if you force it, either. I, however, don't have an SLI setup and couldn't tell you how to force a program into SLI if I wanted to. EDIT: Found a thread describing how to do it. http://www.beamng.com/threads/4262-Guide-Nvidia-SLI-rendering-for-BeamNG-Drive
Thanks for the link, good stuff there. I did some benchmarking tests by driving around Dry Rock Island, with all settings maxed out, no SSAO. With the default setting I had an average of 72 fps, and while forcing Alternate Frame Rendering 2, as per the other thread's instructions, I got an average of 70 fps. I'd say the 2 average fps difference is negligible, so there was no difference. 70 average fps is pretty good, but I'd like to be able to run SSAO without such a frame rate hit, as well as lessen the impact of the random fps drops. The other thread mentioned that the drops might be due to SLI mode not being fully supported. I'll continue to mess around with the settings though. I got far cry 3 to almost double fps with some SLI tweaking earlier, so I'm hopeful.
I ran SLI on my previous computer and didn't seen enough of a real-world improvement to warrant the cost in my current computer. I think SLI is just a stop-gap measure to improve the GPU bottleneck, and won't be around for very long. (soon we'll have multi-gpu-cards, so it won't be needed).
Well, we already have multi-gpu cards. the Nvidia x90 cards and the AMD xx90 cards. I see a large improvement in some games, and not much in others. It really depends on the game. You're right, in the future we probably will see more multi-gpu cards, but single gpu cards will still be produced, and the option to crossfire or SLI them will probably still be around. As far as the current multi-gpu cards go, the still rely on crossfire and SLI to operate because they are still two separate units that need to talk to each other. So, for example, the GTX 690 which is essentially a dual-gpu version of the 680, is just that: two 680's in one card.
