    So I bought the lenovo ideapad y510p with 8gb ram, no ssd, fourth gen i7, and of course the nvidia 750m sli. All of these games are having problems! WoW ran great, but
    1. Dishonored: starts off smooth 60fps, but eventually sticks at awful looking 40fps the whole time, occasionally jumping back up to 60 fps if I look at a specific thing in game.
    2. Borderlands 2: Awful. Just ing awful. 30 fps on the reccomennded settings. It wasn't even in 1080p so that was a ing joke.
    3. Dota2: I think I fixed the problems I was having by setting it to borderless windowed mode. Says I'm at 60 fps, however sometimes I feel like I'm not truely at 60fps.
    4. Battlefield: I feel like I should be getting better fps. With the reccommended settings which is mostly med-high graphics, I often dip to 38fps during casual firefights....

    I'm getting pissed guys. Any suggestions on ways to fix this sli issue? Please don't bother saying laptops suck for gaming, I hear it all the time. We all know this laptop should be performing better.
    For example....these benchmarks are much better

    Thanks a lot for any help you can give me. Tomshardware forums sucked!

    Amm did you pop the second card in ?:rolleyes: as for dishonored 40 FPS on max is for a single 750m.

    If it is in then does the notebook show that you have 2 of them ? Sli migh just be turned off.

    Yeah, the card is in and sli is on.

    it seems as if all of my games like running without vsync on. Like I was saying, dishonored is at 60 fps and then dips to 40 fps at the most random times. but turn off vsync and i'm good to go. 70-120 fps. However, it doesn't "feel" as smooth and there is of course screen tearing.

    And yeah my sli is in and it is turned on.

    Use nVidiaInspector to limit your FPS to 58FPS. It won't Vsync, just limit the top FPS and help smooth things out.

    Why 58fps? I limit it always to 59fps. But yes its probably the best solution. With vsync it feels fungous, without you will get awfull screen tearing (except you get in low games like counterstrike about 200fps, then you won't notice screen tearing much) and with 59fps and vsync/off you get a little bit of a fungous gameplay and one missing picture (but you won't notice it that much).

    But btw:
    Maybe you get low fps, because the drivers are not optimziated yet? For example with my notebook with AMD 7730m I tried when black ops 2 came out to play it, but it was simply not playable duo to low fps. A driver update fixed the problem.

    Are you basing your expectations off of NBC? It would seem there is a discrepancy in their review. Look at the numbers for a single GT750m.

    Dishonored - 44.8
    Boderlands 2- 28.7
    Battlefield 3 - 12.8
    Crysis 3 - 8.1
    Bioshock Inf - 13.6

    Now look at the numbers for the dual 750ms you linked.

    Dishonored - 119.4
    Boderlands 2- 75.3
    Battlefield 3 - 33.2
    Crysis 3 - 19
    Bioshock Inf - 38.9

    ALL games show more than 2x increase for the SLI. Some actualy show almost up to 3x. That is not possible. SLI typically scales about what? 50%? 60%? Depending on the game, it could even show worse results. I won't say your laptop sucks for gaming since you so nicely asked :). However, of all your numbers, only dishonored is an anomaly. Others actually fit the scaling theory pretty well. In dishonored, it is probably a driver thing especially considering you say that stills render at up to 60fps but when the GPUs actually need to render new shapes, it drops.

    I've been going by these
    NVIDIA GeForce GT 750M SLI - NotebookCheck.net Tech

    However, Dishonored is definitely a problem but that is not the only game. Like I said, Borderlands 2, even at basic settings, was locked up at 30-40fps. But, luckily I found the issue in all of my games. Its vertical sync. All of my games that I turn vertical sync off run so much better fps wise. Now I just need a way to make it "feel smoother" with less screen tearing as well. I will try that nvidia tip, any more suggestions would be great.

    You need to run V-sync w/ Triple buffering, which can best be done with D3DOverrider.

    Also I think the 750M SLI has simply been overestimated. They run about as good as the GTX 765M, in the real world.

    Also, one of the problems with Notebookcheck is that they test each GPU on a different machine. Meaning that 750M SLI could have a fast quad core while the 750M had a slow i5

    That will skew comparisons

    Edit: no they were both tested with 4700MQ. I have no idea why they got over 2x FpS because that makes no sense

    Probably different driver revisions.

    Guys it performs very well, I don't find it overestimated. I find the whole "micro stuttering" glitchy b.s. to be the downfall. I'm not saying I can run bf3 at ultra and maintain 60 fps because I know I can't. But on Auto setting at medium-high, it should, and it does, however with the micro stuttering it occasionally "looks" like 40 fps even though it says 60. I don't know much about these issues because I just got my laptop and its my first time with sli, but any tips on fixing these issues would be nice. I managed to fix dota thanks to a borderless window mode, and now it runs fantastic rather then it EARLIER running very glitchy and low frames. There are many quick fixes out there before you can just say "cards aren't that great brah"

    What driver version are you using? If you're using an older driver, it's possible that driver doesn't have an SLI profile for the games you are playing.

    And did you play around with the nVidia Control Panel at all, and manually force certain features to be turned on (AA / AF)? Or are you letting the game control the graphics detail settings?

    I would also recommend using the GeForce Experience to set game graphics settings. It does a pretty good job of figuring out which settings will work well on your hardware.

    I fixed it! All of my thanks goes to you, Kevin, for suggesting the whole d3doverrider thing. It has fixed it and now dishonored runs a beautiful 60 fps consistently and I am so happy. You have taken a load of stress off for me, so thank you. For everyone who jumps to conclusions thinking there is no fix other then "your laptop isn't that great, don't expect much" you would be suprised how many quick fixes there are out there such as this triple buffering and vsync. Thanks again Kevin!

    I just don't see the appeal of SLI when the money could be spent on a faster single core GPU instead?

    You are correct that when dealing with just the GPU, a faster single-core GPU is superior to two slower GPUs in SLI. But this isn't a desktop PC, where you can pick-and-choose individual components and put them together. You need to buy an entire laptop, and you may not like the rest of the laptop.

    The closest single-core GPU that matches 2x GeForce 750M in SLI is probably a GeForce 765M. You can find it in laptops like a Clevo W230ST, Razer Blade 14", and Alienware 14". Some of those laptops have terrible screens (Razer Blade 14"). Some people prefer the aesthetics of one laptop over another. Some people prefer a full 15" screen. Some people are on a budget, and don't want to spend more than $1200 on a laptop.

    You can get a 765m with a 1080p 15" for less than 1200. It's not really a price issue. Choosing a laptop prioritising aesthetics may make sense to some, but not to me. I spend my time using it, not looking a pretty case.

    Are you just experiencing microstutter, OP? If you're sensitive to that, there's nothing you can do to fix it, other than disable one of the GPUs. Microstutter is just part of what comes with dual GPU setups, which is in part why people are saying the 765M is the better option.

    Yeah, it's microstutter I think. Well dang, can I get a refund from newegg?
