I'm running Alien Isolation with my Titan X and am getting ~180 FPS @ 2560x1600 with everything maxed out.

With my GTX 660 SLi I was getting a fraction of that, and I think it's because the game uses 5GB of vRAM (from what GPU-Z tells me).

Anyway, since I have this surplus, I thought of upping the AA, but I can't seem to get a grip on which is the best option.

The in-game options are pretty lax, so I tried forcing 8xAA with 8xAA Transparency, but it just looks worse.

I remember when I used to just have the setting go up to 64xAA and I was content.

Would appreciate the help :)
 
aliasing in alien: isolation is mostly shader based and not fixable with any form of aa other than sgssaa, and afaik it can't be forced to use sgssaa even with custom aa flags. best thing you can do is use dsr.
 
Nothing can fully stop all the crawling jaggies and crazy specular lighting aliasing in that game.

Yeah, I have. Wow! I had no idea DSR even existed!

It's like literally running your game at 4k+ at any resolution, which is fantastic.

I started with 4x Native, which came out as 5120x3200 or 10% higher than '5k', but my framerate went down to 45 AVG, 30 MIN.

So, I went down to 3840x2400, which is again about 10% higher than '4k', and I'm getting about 50 FPS MIN. With adaptive vertical sync, it's a perfectly playable experience.

Hard to believe DSR kicked my Titan X's ass, but I guess 5k will do that :)

The main takeaway from all of this is that, up until now, I saw no reason to upgrade my GPU any further, since games really aren't becoming any more challenging to run.. but since I found out about DSR.. I'm planning on buying two more Titan X's!
 
Yea I would upgrade the rest of your system before you do that. 3x titan x will be severely bottlenecked by a 2600k @ 4.5, lack of pcie lanes and pcie 3.0. Hard has a review up that shows titan x sli bottlenecked by a 3770k @ 4.8

are you talking about the gta v one, where they went back to specifically show that their cpu wasn't bottlenecking them in one of the most cpu heavy games ever released? a 3770K at 4.8 GHz isn't going to bottleneck anything, in any game, even if you're targeting 120-144 fps, unless the game doesn't handle the cpu well in which case nothing would help. a 4.5 GHz 2600K is within 10%~ of a 4790K in multithreaded applications. yes, that's right. i don't know about pcie lanes, and from what op said he's targeting 60 fps anyway, so the 2600K itself is absolutely not going to bottleneck. that being said, since he's even considering buying two more Titan Xs, i see no reason for him not to upgrade even though it most likely would not benefit him.
 
A combination of DSR and some post processing AA is the best antialiasing there is if you ask me. Even measly FXAA people like to shit on starts to look very, very good because downscaling from the higher resolution makes the blur effect disappear. Days of old and tired MSAA are over, it doesnt even work properly in some today games due to the way they render the picture.

No I'm talking about this review where Titan x sli gets the same fps as gtx 980 sli because of bottlenecks

A 2500k/2600k will bottleneck Titan x tri sli @ 1600p period. I used to have both those processors and it's not all about clock speed at the end of the day IPC matters more

yeah, you are talking about the very same thing. click:

http://www.hardocp.com/article/2015/05/18/grand_theft_auto_v_shadow_features_performance_part_4/5

a 2600K is significantly faster in multithreaded applications than a 2500K. of course a 2500K will bottleneck. a 2600K won't, period. intel has barely moved anywhere with their cpus since sandy bridge.

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-2600K+@+3.40GHz&id=868
http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-4790K+@+4.00GHz&id=2275

their cpu scores show how cpus perform in properly multithreaded applications, which is what gta v is. check baselines at the bottom where you can see what a 4.2 GHz 2600K does. you can extrapolate from that that a 4.5 GHz 2600K is going to be at the 10k mark, which is about 12% slower than a 4790K.

now, i'm intimately aware of how cpus perform in games as i target 120 fps. any overclocked i7 from the 2600K on is about what it takes to get 120 or near 120 in most properly multithreaded games, battlefield 4 is the main one where you NEED an i7 to get 120+. OP is targeting 60 fps. in no world is an overclocked 2600K going to prevent you from getting 60 fps in a game. absolutely never, ever.

I would get some gaming benchmarks and try again. A 2500k/2600k will bottleneck in high resolution + multi gpu set ups. The evga link I posted is a good example of that

What's wrong with TXAA? I only run it in MWO but it looks fine. I also force FXAA on in the NCP. 1920x1080 res. Other games I run at 2x DSR.

For me there's just too much bout invloved. For me I find the best combo is smaa + msaa + dsr

What version of the game are you playing that uses 5gigs of VRAM? This game barely uses 1gig of VRAM.

Don't do that until they fix SLI and DSR. Or is it SLI+GSync+DSR?

I don't know, the forums are all over the place on it. SLI+GSYNC+DSR doesn't work for sure yet. DSR doesn't even show up as an option yet but forum reports vary as to whether it's due to turning GSync on or turning GSync on with SLI. Point being wait a bit and read up on it before dropping a few more thousand dollars.
 
I can do DSR with GSync. I should have clarified what I haven't tested is DSR with SLI without GSync--that's the unknown for me and I haven't really gotten a straight answer from any forums (and my second card is en route for RMA so I can't test SLI without Gsync but with DSR myself).

That said, if his thinking is that DSR is a major upgrade and he wants to upgrade to keep pushing to use it then it's worth considering that GSync is a worthy upgrade. Perhaps more worthy? I can't say because I haven't really been able to use DSR but I'd say that Gsync has been a major game changer for me.
 
DSR is not omnipotent though. I know of a few games that it visually made next to no difference (usually the top downs like D3, Pillars of Eternity etc, even CS:GO).

But some games it makes a massive difference, EG FF13. The game is blurry as F even at 1440p, but knock it up to 4k, it makes it much better visually.
 
That's probably why I was unimpressed with it. I'm mainly playing Heroes of the Storm, D3, and Dota2 these days. BF4 is the main FPS I play and I wouldn't bother trying that at 4k.
 
DSR seems to work great in games like GTA5, but how do you fix the steam overlay when using DSR x4?

When I use it the steam overlay chat windows are super small, not really readable so I miss messages. Has anyone found a fix?

That is the downside of DSR. Since you are rendering at higher resolution DPI gets smaller. And if the game does not have ability to control UI size you are shit out of luck. You just have to use smaller DSR value.

With three Titan X's, the best he can hope for on a 2600K is PCI-E 2.0 at x8/x4/x4. That's going to severely limit performance. Even running two at x8/x8 is probably going to be a significant performance hit. For multiple Titan X's, I'd seriously consider going X99.
 
Okay, just to clarify to everyone telling me that my 2600k will limit my performance.

Of course if I'm going to be spending $3,000 on GPU's I'm going to build a brand new rig.

Even though I was being hyperbolic, I don't see much of an upgrade path, though. Would a i7-4790k really be that much faster? It's like a 10% increase every generation. Do games today take advantage of octo-cores?

And in regards to the HUD issues - I've so far not experienced any. On Alien: Isolation, for instance, FRAPS gets super tiny but everything else is fine @ 3840x2400.

But I must admit, DSR has become practically the only reason I am now considering a 4K monitor. Up until now, I simply didn't see the point in such a high resolution, but since I'm running 4-5K on my 2560x1600 monitor, I might as well be seeing the pixels my card is churning out, no?

Any 34-38" 21:9 4K monitors? :)

Well, yeah. Neither Steam nor the game know that you are using a DSR. All they are told is to render the picture in some resolution you desire and the picture is downscaled at the GPU, either with DSR or driver level downscaler. To fix this Steam itself should have a "bigger fonts" or something option built in for people using DSR or those having very small but very high resolution screens. This is something they cannot do automatically.

It's not the CPU itself, it's the PCI-E lanes that will make the difference with Titan X Tri-SLI.

4790K would still be x8/x4/x4, but PCI-E 3.0 (the same as x16/x8/x8 PCI-E 2.0).

I wouldn't go Z97, though. X99 or bust! Get yourself some x16/x16/x8 PCI-E 3.0 goodness!

Oh, no. I realize that. I was merely debating the CPU bottleneck side of things.

PCIe 3.0 definitely seals the deal if nothing else does :)
 
As game dev and someone that knows every AA method, SGSSAA x4 with a -1.0 Mipmap Bias is the best AA. Super sharp textures with zero aliasing. Also you don't run into the UI issues introduced running at higher resolution like with DSR for some games. DSR is the next best and easiest for most people.
 
Before you run out to buy another videocard for the use of DSR, be aware that DSR does NOT WORK in SLI in almost 100% of games. It creates a flickering that isn't playable and anyone that has tried to use dsr with sli enabled can confirm this as I even went as far as to ask nvidia about it. There official line is that DSR is not currently supported in multi-gpu setups, which really sucks since you essentially need multi-gpu setups to get solid framerates at the 4k dsr resolutions. Anyways, it is fun to use in older titles that you can really max out now.

Does the driver level downscaling work? Set the scaling to GPU and create a custom resolutions higher than your native resolution. If it does thats a one workaround. It does have a simpler filter than DSR but otherwise it looks good.

I think it SHOULD work for SLI, but 120hz can cause issues. 60hz is a max for the GPU scaler i think.

Not sure how you have that issue. Dsr + sli has always worked for me. And this is in every single game I've played since it came out (basically all the main ones)

DSR + SLI doesn't work with G-Sync.
