3840x2160, G-Sync and one GTX970

After knowing that Devs has no plans to implement the Oculus DK2 in BOS, my only option for the next year will be to play in a decent monitor.

 

So yes, Santa brought a new rig and new monitor. My doubts were 4k or 2k, G-sync or no G-sync. that´s the question?

 

I already had a GTX970 with my 5-years old rig, and after reading many opinions I was not sure if a single GTX970 was going to manage 4K properly.

Finally, I chose the Acer XB280HK, which is the only 4K monitor which currently support G-sync. My previous monitor was 19" 1680x1050, so a big jump.

 

Yes, it is "only" 60Hz and one would think that 60 fps could be not enough for a flying experience. One of the reason I deciced the XB280HK was to test it for myself instead reading the opinions of others with no G-sync or no 4K.

 

My initial plan was to acquire another GTX970 or to play with 2K(2560x1440), if the 4K were not well supportted by one single GTX970.

 

I have just made some performance test with Fraps and this is what I obtained (All test are done with High Settings, clear sky and BF-109)

 

With 2K and Antialiasing x4:

60fps at normal landscape

55-60 fps at low fly in Stalingrad

 

With 4K and no Antialiasing:

60fps at normal landscape

30-60 fps at low fly in Stalingrad, most of the time in 45-55 range

 

You would ask:  Is the 2K fly as fluent as the 4K? The answer is absolutely yes, at least for my humble eyes. There is no tearing, no micro-delays in the image and very smooth.

 

I have also tested to deactive the G-sync from the Nvidia panel and then the fps remain the same but with you can quickly see the tearing and anoying defects. It can be very well seen when you fly in third person (pressing F4) over Stalingrad.

 

I think G-Sync is more than a marketing name, it avoids the need to go to multiple GPU to obtain higher fps with 120Hz monitors.

 

So my conclusion would be that a single GTX970 can handle well 4K if G-sync is used.

Also, in a 28" monitor with 4K you don´t need to use the Antialiasing filter. You can see that in the attached raw images where no AA were used (use Google drive since they are bigger than 5Mb!):

No need to say that once you play at 4K you don´t wnat to play at 1080 or 1440 anymore.  ;-)

 

Hope it helps to others in their hardware upgrades.

I'm running 2x GTX 980s and hoping Santa brings me a 4K monitor...

I am able to get good frame rates with DSR set to 4.0x which is 4K like an average of 65fps over Stalingrad in an 8x8 Quick Mission

as far as refresh rate, I don't think you're going to see 4K video go above 60hz for some time, most cables can't handle that

watch out for HDMI 1.4 as it will only handle 4K/30hz. HDMI 2.0 can handle 4K/60 and so will Displayport 1.2
