130FPS with 2xTitan Black on 4k - but just for 60sec

[BitMaster]

SkateZilla,

 

is there any HDMI 2.0 out yet ?

 

I do know that 4k needs at least DP 1.2 for 60Hz and DP 1.1 for 30Hz.

 

any DVI or HDMI 1.x will only do 30Hz.

 

Thunderbolt I will only do 30Hz too afaik ( my MBP ), only Thunderbolt II delivers more Hz.

 

 

4k will be standard in 2 years, cheap and everywhere with connectors readily available for 60Hz.

 

Right now, most good 4k screens are in the 1k € and up class and beyond reach for most of us.

 

 

IMHO, SLI is causing more trouble and pain than it does good with most games.

 

 

The real deal was EF2000 and 2 x Voodoo-2 cards with 32MB VRAM in SLI in addition to a Matrox-2D card...LoL

that's almost 20 years ago...but it really gave you 98% boost... and ultra smooth edges at 800x600 :)

 

ol' glory days

I have same CPU but clocked at 4.6. And sli 770 at 4gb. Same thing but it's the ai and object count that hammers the processor. Hence why gpu usage drops nothing can be done unless more optimizing and usage of more cores for ai and other routines. Hopefully edge will help with all the fancy graphics fully offloaded to gpus

HDMI 2.0 can do up to 4096×2160p @ 60Hz

 

AFAIK, there are No AMD GPU's With HDMI 2.0, Nor nVidia

HDMI 2.0 Was Paper Launched Last September (2013),

So You likely wont see it until a New GPU Family is released as both companies would have to embed a new HDMI Controller into the GPU Architecture or on the PCB.

 

IMHO HDMI is redundant,

DisplayPORT allows for multiple Streams through a Single Cable or from a single output to a MST HUB.

DisplayPORT 2.0 is better than HDMI 2.0 in Bandwidth

HDMI Charges a License/Royalty fee Per Device and $10,000 Per HVManufacturer for everything HDMI. TVs, Cables, Monitors, Sound Systems, Everything.

DisplayPORT 3.0 is about to be released which doubles the bandwidth to 32+Mbit and allows for 8K Resolutions@ 60Hz on a single cable. or 2 4K Streams @ 60Hz , So In Theory, one could Drive 8x 1080P Screens @ 60Hz from a Single Display Port w/ a MST Hub.

So basically what you're saying is DP 2.0 better be included in next gens video cards. =P

Imagining running DCS with a monitor set to those specs. in that resolution gives me goose bumps. Man would that be awesome!!!

DP 2.0 is already on AMD 6000,7000, and R Series, and nVidia Counterparts (700,600,500 Series and likely 400 series.)

OK so I should get a screen that supports DP 2.o for my 7970 card? Any recommendations?

[SkateZilla]

I think only ASUS and Samsung have 4K 60Hz over DP2.0 Screens.

[Dav IRL]

I use sli , 2 screens both at 1920 x 1080 and I get between 50 and 100 frames . I get occasional cloud flicker but only occasional so I cannot complain. With one card and ONE screen I get the same fps but as soon as I add a second monitor I drop to 50 on average with one screen. Soooo, if you want multiple monitors then sli IS worth it to have the game running at such a high frame rate, sli is commonly disregarded and I have no idea why because it gives me high frames, higher frames and a second monitor to use as a targeting pod.

[AtaliaA1]

And your Video Ram is?

[infernus1986]

Your confusing DP 1.3 and HDMI 2.0

DP 2.0 isnt even a theoretical standard yet

Additionally not all the cards you listed support HDMI 2.0

Lastly SLI/Crossfire is a gimmick, have fun trying to get it to function properly without causing rendering errors.

[cichlidfan]

And your Video Ram is?

 

The label on the box says 4GB for his video cards.

I've been using the ingame fps counter. When it drops from 130 to 50fps the external (NVIDIA) SLI bar also drops from 80% to about 30% GPU load.

So it's not just the fps counter that's acting up here.

Dude, in my experience with DCS and PC simming in general, I reckon it's a CPU related "issue" (not really an issue, it is perfectly normal).

 

As you start the mission you are far from the battle area - basically there are not many objects to render around you.

 

As you approach the battle area, tanks, vehicles, soldiers, helis and aircraft start appearing, and their 3d models need to be rendered, the nearer you are to them, their LODs getting more polygons.

 

This condition alone means that your CPU, which early was calculating say some hundreds of points in the 3d space, now is crunching numbers for tens of thousands of those points.

 

So, the processing power is the same but the CPU workload goes up exponentially. So the GPUs, which must wait for the CPU to resolve an entire frame made of points in the 3d engine, work less, because the CPU needs more time to process a scene which is much more complex. The GPUs hence, work much less, and you see that effect represented by reduced fps and also by the indicators you mentioned.

 

With the current engine, to keep running 130 fps (which is useless anyway, a stable 45 fps ALL the time would be a blessing, and you wouldn't notice any difference, fps wise),

you would need CPUs which are basically yet to be designed.

Moreover, even if you would get those, you would still notice a difference in your fps counters pretty much the same way you described (would be like, 250 fps at the start, 100 fps later).

 

Since DCS is a complex 3d environment, made for a combat simulator with hundreds of entities in it, fps don't really matter much, as long as they are stable above 30-40.
