HappyCapybaraFamily posted:I recently upgraded to a GTX 760 and am using my old GTX 480 as a dedicated PhysX card (and electric bill increaser). I obviously have more dollars than sense, and now I am thinking of replacing the GTX 480 with a used GTX 650 Ti for PhysX duty, but will I see a performance increase? I will at least see my electric bill go down a dollar or so a month, probably, and gaming won't give me heat stroke in the Texas summer, at least. I went from a GTX 580 for PhysX to a 650Ti for PhysX and have not seen a performance decrease, but I also haven't seen a performance increase. About the only PhysX workload that I've found that can even really get the card to stretch its legs is FluidMark, and that's sort of to PhysX what Prime95 or whatever is to CPU overclocking, it's got a mode specifically made to run it as hard as possible. There, my GTX 650Ti looks like a puny lil dude compared to my 780Ti, but that's to be expected. In games, the only difference going from a 580 to a 650Ti was power savings. You could probably save even more by going with one of the Maxwell low power cards that have come out recently. PhysX in games is not a hard job for cards to do; you'd have to have a pretty much bottom of the barrel card for it to suck at PhysX.

Thanks for the advice! I would definitely go for the 750 if I could find it used for the prices I'm seeing for a used 650 (less than $100). Though taking into account the power savings, it might be worth it. v  v

After like 2 hours of loving with vsync settings for SLI, simply capping the FPS at 59 and turning it all off is far superior than vsync (input lag), vsync smooth (random drops to 30 fps, input lag), and adaptive (utter garbage). Just tested for BF4, but I wonder why that isn't just an option to begin with.

It's even 80 Plus Titanium so you can save on those power bills This might be an option, especially since no one has any of the drat psus in stock at msrp that I'm looking at. If anything I think I'm going with the EVGA 1300 assuming I can find it in stock because it's only 229 @ evga. gently caress Newegg and their price gouging, they want 359 for it. As for the current power supply being worn out, I have only had it in service for the last year or so. It literally would not power on with the EVGA x58 board as it thought there was a fault. So it sat on a shelf for 3ish years. Cool thing is, I can actually disable the third card on my board using the dip switches until I get a better psu. Also, Titanfall comes out next Tuesday. Wewt.

Some say 59 because the last frame is part of the next second or something but that doesn't sound right to me. What's the official word for what I should be doing in Precision X?

I know for a fact I wouldn't notice the difference though, and if there is any chance for it to cause a problem it isn't worth it of course. I'll try it out though. One thing I didn't take into account is how much less work my GPU's are doing now, where vysnc was intense on them for a worse result.

I use EVGA Precision X to limit frames, if I recall it's the only one that works on both 32 and 64 bit games. Stupidly it only goes up to 120hz when plenty of monitors do 144. Edit: enabling Vsync usually caps any game to 60fps as well but with V sync off a lot of cards will stupidly try to push 200+ fps in Call of Duty, etc. Zero VGS fucked around with this message at 18:04 on Mar 5, 2014 |

I was getting 120-180 fps with some occasional stutters with vsync off in BF4 so thats what led me to give vysnc a try. Immediately impressed then immediately disappointed. I'm just glad frame limiting accomplished the same exact thing without any of the consequences so far

Yeah if you can hit a solid 60fps you want to frame limit, Vsync will add input delay and lower the overall framerate. Frame limiting is absolutely awesome for SLI / Crossfire, I like to adjust the settings so I'm getting 60 fps with both cards at about 75% load. That way the cards are ready to crank themselves up and prevent any frame drops, but they're also comparatively cooler/quieter together than a single more powerful card would be.

Right now I have an MSi Radeon HD 6850 Cyclone, but I'm looking to upgrade so that I can play BF4/new games without much issue since I've had this GPU for four years and it's starting to show. Which would be a better upgrade: buying a second matching GPU or buying one different GPU to replace the 6850? My budget will probably be $250 max, and if I remember right, most games can't really use crossfire very well anyways...

I know its different tech and all but have you tried vsync off and setting a frame limit? Basically all info online talks about combining the two, but very little suggests just trying the one. Frame limiting and vsync did absolutely nothing for me different than plain vsync, contrary to what a lot of people have reported improvements with. I tried to convince myself the input lag was in my head but I just couldn't get over it.

Now, I've never swapped out video cards before, so is there an easy way to uninstall the old drivers and install the new ones? I'm pretty sure video cards are plug and play so it should install the drivers on its own once the system is fired up, right?

Tusen Takk posted:Good stuff, cheers! You should always download the latest drivers from Nvidia (or AMD whatever you get), dont use the CD. It will give you a picture when you boot but that's it (if you just put a new card in and nothing else). I'm pretty sure windows update will get you drivers but you really should get them from the manufacturer website. When I swap cards I always download the new drivers first, completely remove the old drivers (sometimes this isn't the simplest thing) then install the new card and then apply the new drivers. And just for options sake the R9 270X is similar to the 760 but since you specifically said Battlefield 4 in there I have never seen a benchmark that shows the 270x doing better head to head. Plus its generally a little more money. Others probably know better than me on AMD cards but yeah I guess parts picking thread for that stuff Ignoarints fucked around with this message at 23:02 on Mar 5, 2014 |

I got a lot of mileage out of my 965 BE :P. Overclock it if you haven't, makes a huge difference for online multiplayer especially if your GPU is no longer the bottleneck. Actually in fact, I got up to 60 or 70 fps in BF4 at ultra with 0x MSAA with that AMD. It would dip to the 40's sometimes, but I was impressed. That was with a GPU with less memory bandwidth too. Getting a better CPU certainly helped to keep it out of the 40's and 50's though. That was at 3.8 GHz I believe, a fairly mild overclock for it.

That's the same price as the 4GB 760 "B-Stock" on EVGA's site. If you can apply the discount to B-Stock then that'd be really insane. Edit: I kinda really want a part-time job at Microcenter just to be able to buy graphics cards at cost.

It ran really cool. I also had something bigger on it but it was unnecessary. I never had any kind of lock ups with mine stock or overclocked there is probably something else going on there, but this is definitely for another thread now lol

But there's a reason Vsync has been the best way (and only way, for a while) to prevent micro stuttering in Crossfire configurations. It's pretty much the only way to guarantee that one of the cards won't be issuing a runt frame. To be fair, I think that my issue isn't so much Crossfire itself as my motherboard's hilariously uneven PCIe bandwidth. As I've mentioned earlier in the thread, the secondary PCIe slot goes through the PCH and so only runs at x4 1.1... Alongside the primary PCIe slot at x16 2.0. Given the fact that the micro stuttering (and worse stalls in general) normally happens in situations when new data gets streamed in, I wouldn't be surprised if Crossfire is somehow failing to account for that disparity. At least Vsync seems to force them in lockstep. I don't mind, as I've never even noticed the dreaded input lag that apparently comes with Vsync.

Zero VGS posted:Yeah, you might take a look and see if you need to take a can of duster to it and/or redo the paste. Duster and paste are both really cheap so you're not out much and you might keep the thing alive longer.  The aluminum fins on the heatsink were so clogged with dust that I had to go at them from both sides 3 or 4 times just to get the dust bunnies out and I went through half a can of air cleaning the whole thing. The thermal paste was pitted and brittle, I'm not sure what the stuff looks like when it overheats but I'll bet that's what happened. I was getting 12fps at 99°C on the FurMark burn-in test before, I'm getting 19fps@69°C now. I'm going to be a lot more proactive about cleaning my computer now and at least check the heat sink I can't see into with a small mirror next time.

Alereon posted:Honestly it seems like it would make more sense just to get two somewhat smaller, high-efficiency power supplies. It's not a huge deal but bumping up the efficiency would also give you a bit more room on your circuit before you pop a breaker. As an example, the Rosewill Tachyon 1000W is $199.99 at Newegg (though currently out of stock), and while Rosewill isn't a high-end brand the Tachyon is a decent SuperFlower model with good component selection and build quality. I think one of these should power two R9 290Xs alone no matter how hard you push them. The EVGA is pretty much 90% efficient. I don't want to deal with the hassle of putting multiple psus in my case. Plus I'll be able to sell this one to recoupe a bit of my cost.

I don't think it's a bottleneck for me though. I set the FPS to 60 yesterday not expecting much but it was actually smoother than 59 fps in that there were virtually no stutters, but I experienced obvious, reproducible tearing for the first time so far. Also, very very occasionally it would tank to 30 fps or something for a second regardless of how much or little was going on - something that would never happen with everything off (or 59 fps) but would happen constantly with most vsync modes. I dunno, confusing, I'll just leave it at 59.
