The_Franz posted:OpenGL has actually had things like multi-draw-indirect for a few years now which lets you concatenate thousands or even tens of thousands of draw calls into one. People are only just noticing now because Valve has started dragging the entire industry away from it's Windows-centric viewpoint. It's a lot less valve and a lot more iPhone that's been the drive toward opengl the issue is that ensuring that extensions are supported on all of your client platforms is a complete pain. DirectX at least lets you know that if you program to DX11, you get all of DX11 features. I suspect we'll see implementations where one is optimized for XB1/DX and one for whatever PS4 runs (Mantle?) before we see people explicitly optimizing for OpenGL on the desktop.

Malcolm XML posted:It's a lot less valve and a lot more iPhone that's been the drive toward opengl OpenGL and OpenGLES on mobile devices are two different beasts. Most of the techniques and optimizations they've been discussing at recent developer conferences aren't applicable to ES. Fragmentation isn't really a problem as long as you pick a core spec and stick to it. It only becomes an issue if you really want to use some of the bleeding-edge or vendor-specific features. None of the consoles support Mantle and probably never will. The XB1 strictly uses D3D and the PS4 has it's own proprietary low-level API similar to the PS3 as well as an OpenGL implementation (and I think a D3D emulator on top of that) for more easily porting games that aren't bleeding-edge AAA titles. On the desktop, more and more companies are already starting to target modern OpenGL targets. Some slides during a presentation at Valve's dev conference gave away that Epic has been working with Nvidia to optimize the OpenGL backend in Unreal Engine 4 and both AMD and Nvidia have been improving OpenGL support in their profiling tools as well as porting them to Linux, so there is definitely some developer demand for it.

4K seems to be on the horizon at this point. The ASUS PB287Q is going to do 4K @ 60hz for $800 sometime in Q2. What kind of GPU are you going to need to drive something like that at reasonable (non-Ultra) settings?

fletcher posted:Any chance we'll see g-sync in these 4K displays? Would a 4GB 770 be able to handle gaming @ 4k? As to the former, who knows, but the 30fps floor makes it an unlikely use case for any single card to handle well. G-Sync is ideal for framerates between 30fps and 144fps, but it ceases to function at 30fps and below (reverts to traditional VSync). Given that these displays are 60fps displays, that would mean going back to very low framerates, and without the direct quality that G-Sync gives for the mid-40s FPS in the demos that we've seen so far. I'd think two high-end cards would be the minimum for acceptable gaming quality at 4K resolution. But, we're also at a point where two high-end cards can actually make 4K pretty nice - check Anand's 2x780Ti vs. 2x290X GPU bench comparison, which helpfully includes some 4K tests. Many games are at nicely playable average framerates. That high of a resolution will bring out any AMD-advantage games very substantially because of the higher pixel throughput - anything strictly geometry bound will benefit from the substantial ROP advantage that the 290X enjoys, 128 combined ROPs vs. less than 100 ROPs from nVidia's GK110. But, then, that's "last gen" hardware from nVidia still keeping up quite well. I'm not even going to try to gently caress with the value question since prices are all over the place for AMD hardware but ideally you'd see the original street price of the R9 290, $400 stock but add more for vendor specific cooling, leading the price:performance charge with nearly the same level of performance seen in the 290X in that comparison for about $880 accounting for buying units with nice custom coolers from various vendors. However, individual 290 and 290X cards are going for nearly a grand now so that's all shot to poo poo. Maybe a pair of 780s instead, they're not that far behind a 780Ti. Significantly less overclocking headroom, but overclocking is trickier when you're running multiple cards anyway, and is probably even less of a good idea than OCing for general usage.

FYI my eyefinity setup is a higher resolution than 4k and BF4 plays pretty drat nice at Ultra, but this requires 3 290x cards. So I'm guessing we're still 2-3 generations out from a single card maxing out a single 4k monitor at 60 fps. Which by that time, maybe 4k monitors will be affordable.

I tried this with my 7950 sporting new paste, VRM/RAM heatsinks, and fans, since they're still going for $400-ish on eBay, and no one went for it without a hilarious lowball in the process. A safari through the Reddit Scrypt boards revealed that since it's mostly Lite/Dogecoin retards buying these, no one wants ANYTHING custom that would invalidate the warranty, because they're all in an endless cycle of frying their VRM's, RMA'ing the dead card, frying the RMA's VRM's, repeat. The Radeon stock problem could probably be helped to an extent if manufacturers didn't cover self-destructive users who stress the gently caress out of their cards with inhuman amounts of load 24/7

for like the fifth time, nobody important was mining bitcoins with GPUs anyway so mtgox doesn't really have anything to do with anything. The cards just aren't as inflated as they used to be, at least at the high end. It might still be worth flipping crap cards if you want a cheap upgrade and your card's still under warranty. I've been checking ebay occasionally out of curiosity... I certainly don't regret my pair of 290s; this is probably the best price:performance you can get for any kind of reasonably high-end setup (aside from 3 or more 290s  ), but I'd still happily flip them and switch to 780Tis if it made sense. 290s only go for like $450 after fees though so makes zero sense. 7950s are ~$350 before fees and 7970s a few bucks more so seems just barely worth the trouble for those, at least.

People do that since you can't directly cash out many altcoins (though I think you can cash out litecoins), but you haven't been able to get money or bitcoins out of mtgox for like months now, so legit miners cashing out frequently shouldn't have gotten hosed by gox, only people speculating/buying toxic goxcoins who rightfully got the gently caress burned out of them just now.

It's a lot of money, yeah, but people spend that much on a nice TV or a SLI graphics setup no problem. And for non-gaming use, the prices are already there. You can pick up a 39" Seiki 4K TV set (aka a large monitor) for $500 any day of the week. They dipped down to $400 a couple weeks ago. The downside is of course it's HDMI 1.4 therefore limited to 30hz. I'm thinking about one of those 39" screens if they go on sale again at some point. That's a bunch of working area and 113ppi isn't awful. It seems like a no-brainer for computer-folk who spend all day staring at a screen.

I feel like $800+ plus another $800+ worth of GPU just to run one 4K monitor acceptably is kind of a step backwards for a lot of games, if I were going to do something crazy like that (well, crazy as it stands right now) I would just as soon consider 3x1440p eyefinity or like 5 1080p debezeled monitors in portrait or something fun like that... taking a break from posting now

Man, I used to set up with seamless displays a lot for work (46" 1080p each and 5 grand a pop) and I can't believe I never thought to hook it up to a sweet computer. The average size was probably 4 high 5 across. Would have been pretty cool. Right before I left I set up a hoist for a 20 ft x 60 ft projection screen and I really was dying to play a game on that. Needed 3x $100,000 projectors to look nice but it looked amazing.

Zero Gravitas posted:Welp I found out that the reason why my PC keeps shutting off while gaming or leaving to run CFD simulation overnight is that the cooling fan motor on my graphics card was hosed and at an idle temperature of about 60 degrees its probably not going to last too long. There's not going to be any banging at that price point. Do you have an intel CPU with integrated graphics to fall back to? If you do, then you should subsist on that untill you can afford to buy a real graphics card - something like a gtx750 (around 90 - 100 pounds) for bare minimum 1080p medium - low settings stuff, or a 750ti ( ranges from 100 to 130 pounds) for acceptable medium to high settings performance.

Alereon posted:Yeah It seems insane to me to invest in a setup for 1440p gaming with only 2GB of RAM. While current games largely do fine, I don't see how you can expect that to remain true at 1440p through this summer, or 1080p for much longer than that. Maybe I'm chicken little, but it feels like people set their expectations for VRAM demand growth during a time when it was historically low due to constraints from old consoles, now that that's not an issue we're going back to "normal" so you can't get away with underbuying on VRAM the way you used to. I focus so much on avoiding VRAM paging I can't really think of anything that ruins your gaming experience like running low on VRAM does, especially in multiplayer. Having stuck with a 512MB videocard longer than I really should have, it's drat important to me to avoid living with insufficient VRAM.

I have an ASUS 660 TI bios modded, repasted, and overclocked, but it runs super cool and with great numbers. I'm buying two MSI 660 TI's used that were never overclocked and are about just as old. Should I SLI the two MSI's or should I revert the ASUS back to stock bios and add one MSI? Would there be any difference in ease of installation or compatibility at all? I'd just go ahead and do both MSI's but I feel as if the ASUS has been devalued for resale in general despite being really awesome. I'm going to be selling one of them, just have to figure out which one.

It would be really difficult to find your max clocks this way since undervolting could potentially reduce stability, and you're changing at least 2 variables at the same time.
