Hi there, my name is EknineEd1385 and I have a question for the community here. Before I start, I would like to give a few prerequisites to this post:
1) Yes, I have searched the internet for answers to this with zero return.
2) I would greatly appreciate some experienced answers from people under the same circumstances as opposed to speculation.
I was wondering if SLI can be utilized at all for the Shaders mod, and if so, how much of a performance yield would this show? Currently I'm running a single GTX 970 with an i5 6600k. I run my game at full 1080p, and like to super-sample the resolution to 1440p or so. The performance is decent, (around 70-90 FPS or so with my favorite shaders,) but I would like to upgrade. I am also getting a new 1440p monitor with a refresh rate higher than 60, so the upgrade is a little necessary.
I want to grab another gtx 970 and configure SLI for 1440p performance in my other games (Triple A titles) to avoid having to spend a fortune on the pascal cards and sell my current 970, which would be quite a hassle. I was wondering if (ANYONE WITH EXPERIENCE) could answer this question for me:
Is Nvidia's SLI compatible with Shaders, and does it yield a considerable performance increase? If so, is there anything special required to get it to work right, and if so, what would that process be aside from standard SLI configuration?
SLI is made to connect multiple GPU's together to generate one single output. Yes, it should work. Getting another GPU may not support your PC, you have to look at your motherboard if it supports a second GPU, and your power supply if its high enough to support a second GPU. Its not as simple as you think.
Factor in your PC will have to work to keep cool two GPU's instead of one, causing temperatures to rise.

Thanks for the reply, I appreciate your time.
I'm aware of how it works, and my specs are totally fine. I have the means of getting another GPU, I have a power supply to support it, motherboard to support it as well, keeping it cool, etc. etc. I built the thing for Pete's sake. But, I've been seeing a lot of complaints saying there are problems with it but not a single person actually confirming that it does indeed work properly.
While theoreticallyit should work, I've been seeing a lot of complaints that:
1) Not utilizing the GPU's to the proper extent (%), or
2) Proper % usage, but having even lower FPS than before.
OpenGL 2.1 isn't exactly the most intuitive backend, and I don't know if this causes these issues, or if it's Minecraft's code itself, or something else. I was hoping for a confirmation from someone actually using an SLI config to confirm or deny that it actually works before I waste money and find out it doesn't. From what I'm seeing it looks like it's screwy and I would like some first-hand feedback.
Java does not use SLI. Period. There are no profiles provided by Nvidia for Java, as such SLI drivers don't know HOW to work with Java.
There are ways of forcing SLI use, but they cause a massive performance drop due to lack of a driver profile. When forced SLI will run in a default mode that, among other things, will try to synchronize texture data between both GPUs. Each frame. Over a very slow data bus.
End result is that forced SLI runs up to 50% slower then single GPU.
There are known workarounds but they have to be applied to the game's base rendering code. And I'm not sure if that is possible with mods, or if it requires a deeper overhaul.
Thank you^^ This is exactly the answer I was looking for. Very disappointing to see that an SLI config won't affect anything, hence why I posted this inquiry before making my decision. I'll probably still go for an 970 SLI config to have my AAA games run well at 1440p, but as for shaders it looks like I'm a bit screwed.
While part of me likes Minecraft being in Java for stuff like my plugin/mod development, the other half hates it due to stuff like OpenGL, inability to SLI, optimization crappiness, and tons of others. It's such a shame.
SLI is a waste. One can always wait a generation or two and get a single card with the same performance, using less energy. Or you could grab a second card and deal with all the rubbish that goes with getting SLI running.
That's just my opinion in general; SLI with Minecraft in specific has already been answered
