Benchmarks of new 4k Sager 15'inch?

Sager Custom Laptops

This thing has a 4k screen and an 8GB 980 GTX card, do you think this thing could handle most games at 4k 60 fps?

 

Maybe with low settings.

 

Honestly, if you're avoiding unoptimized AAA stuff like Watch Dogs, it'll be fine with high/ultra settings at 4k, especially if you're leaving off multisample-type AA like MSAA/TXAA/etc.

It depends heavily on the game though.

 

A dozen or so benches at 4k here: http://forum.notebookreview.com/sag...-impressions-review-htwingnut.html#benchmarks

I can say that it ain't pretty. It's basically asking the GPU to drive four 1080p display simultaneously. But I do have to say that it scales well to 1080p.

I ran them at "ultra" or maximum preset and then also at "medium" which was whatever was middle of the pack preset, and made sure there was no AA active, and it did get playable frame rates then.

 

^Looks like even at low, 60 FPS wouldn't be guaranteed in demanding games. Single laptop GPU (or desktop GPU for that matter) simply isn't enough for 4K gaming.

 

For now 4k gaming on laptops isn't possible. I recon it will be another two or so years before laptops may drive games high detail 60FPS at 4k.

 

I thought the 4k displays didn't require AA due to the high res or whatever so don't know why there's so much fuss about no AA... Anyways, 4k will be fine but don't expect miracles... I would say on the safer side, just get a 1080p LG IPS display..

 

Even without AA it's a massive stretch.

 

You know, I always found it weird. I've been able to use 4x SSAA + other AA + ultra in quite a few games and still never drop below 30fps in many games with my 780Ms... if a single 980M is ballpark what my 780Ms do, I don't see why it's so low in those instances?

Sleeping Dogs' "extreme" AA is that kind of SSAA, and I don't get below 60 there usually
Sniper Elite V2 I can use 4x SSAA + "high MSAA" in game and never get below 60
Tomb Raider I can run perfectly well with 4x SSAA and "ultimate" quality (tressFX off)
Trine 2 doesn't even go below 80fps with 4x SSAA enabled and ultra graphics
Advanced Warfare is pretty much fine too with 4x SSAA and 1x SMAA

I wonder if drivers were the cause? Or if not, then running on native 4K screens must be MUCH more demanding than using DSR or SSAA.

 

Recent games are a lot more demanding/unoptimized than Sleeping Dogs, Sniper Elite V2, and Tomb Raider. Those games came out 2-3 years ago, well before the current console gen.

 

Yes, however I listed Sleeping Dogs and Tomb Raider etc because they were in Wingnut's bench list, which apparently needed medium settings to get what I get here. Which is where my confusion begins.

Either way, I always say new, unoptimized, AAA titles will suck at 4K, but anything prior should be fine.

 

Don't forget that your 780M SLI has twice the memory bandwidth of single 980M, which plays an important role at extreme resolutions.

And like I said, the arrival of current-gen consoles raised system requirements of PC games quite a bit, as it has in the past. Whether the new games are really that demanding, or just poorly optimized, is up for debate. But the increase in system requirements is not.

 

I really should check the memory controller load under 4K gaming. At 1080p it usually sits near ~16-20%, and vRAM usage doesn't increase greatly with the resolution bump usually; I don't get why memory bandwidth would get stressed 3x as much just with the resolution bump. 16-20% = 36-40% of 1 card, so even a 2x increase tops out near 80% of the controller's limit, which means that it shouldn't make a dent in performance unless it's more than a 2.5x for such games. Also, Maxwell is supposed to have that "efficient" update to the memory controller, which makes the bandwidth stretch further, apparently. So it'd need to be even more demanding, no?

I'll do some testing later probably. Whenever I get around to it. Sometime. Maybe. I'm lazy today.

 

I can compile lists for the games that achieve maximum graphical settings at 4K/60fps and 4K/30fps respectively. I will report back soon(ish).

 

Let us know how it goes.. Also are you going to be writing up your review of the P651SG? Will be interesting to see...

 

If you could check your memory controller load (and if OCing memory slightly helps FPS) as well, that'd be great.
