Are you able to test a few more games on bootcamp, like bf1 or rust and maybe even PUBG?

Not in this case though.
This isn't simply a UHD monitor scaled to 1440p, instead it is a monitor that, in 1440p mode, uses exactly 4 pixels for each pixel. The 5120x2880 is double in both directions, so running at half resolution will keep everything running along pixel borders. It doesn't need to do any aliasing since it can just use 2 horizontal pixels and 2 vertical pixels to represent 1 pixel at 2560x1440.

Don't have BF1 unfortunately, but I do have PUBG, will test it out tomorrow and let you know
No, it’s not true. We are talking about 5120x2560 not UHD. 1440p is the same as how you see the desktop scaled 4 pixels to one or 200%.

I was using 2560x1440, same as you!
What were your GFXBench Metal Numbers?
Mine are almost identical to these -

I must have something set wrong in Valley if the scores are coming out the same...
OK, right, not UHD (3,840 x 2,160). It's a HiDPI monitor, which is what I meant. If you drop the resolution in an application to 1440p on the 5k iMac, it's not going to look as sharp as a monitor at 1440p. There are a ton of threads on this forum about, it, and it obviously can vary by application and what a person is sensitive too.
Go use an application like Display Menu, and look at the difference between 1440p HiDPI and regular 1440p on your Mac. Some applications or games will look blurry similar to this.

This guy ran a bunch of boot camp game tests and puts up stats at 2:37 of his video. He showed overwatch at 72 fps, BF1 at 62 and PUBG at 52 fps all at 1440p with highest settings
60 FPS you should be able to sustain in 3840x2160 in Overwatch on High settings. That is actually weaker score, than I thought.
Unfortunately, because of the version of macOS I am running, GFXBench will not run.
So it appears there is no consensus regarding that issue. Have you personally compared the 5K to an equivalent 1440p monitor?
I see now reason why the same 1440p image should be more blurry on the 5K. Maybe that could result form some upscaling algorithm that introduces some smoothing (hence blur).

I just ran the Valley benchmark on my 27" iMac with geforce 775M and I got the exact same result. I have the feeling this test is CPU-bound if run on powerful GPUs, since it's not that graphically intensive and not really multithreaded.
I used an Apple Thunderbolt Display with my 2014 iMac 5K and the 5K looked much sharper in HiDPI mode (so pixel-quadupuled 2560x1440) than the Thunderbolt Display looked in native 2560x1440. I didn't play games on the TB display so I cannot comment on that, but everything else (Safari, Chrome, Office, video, etc) looked better on the 5K display.

I’m sure that is correct.
A technical point though, it is pixel quadrupled, not doubled.
Super impressed with the Radeon Pro 580 from his video. Especially when you consider this is at 1440p. This is easily desktop GTX 970+ level performance.
Barefeats has posted their first iMac 5K with the 580 GPU benchmarks: http://barefeats.com/imac580.html
Interesting. The Heaven result looks weird though. Could be that the 580 is not optimised for OpenGL with Metal being the way forward. Don’t know.
Well that's obvious.
We were discussing a game running at 1440p, which according to some would look better on a 1440p display than on a 5K display.
Your desktop showing on a 5K display is a 5K image, not a 1440*2560.

This benchmark makes no sense. I'm getting better results than the 395X at the exact same settings with my piss-poor 775M.
EDIT: it was the Valley benchmark. Still, the radeon cards are clearly penalised in unigine tests.

This continuing discussion is crazy! A game at 1440p on a iMac 5k screen will look exactly the same if not better than on a native 1440p monitor. At 1440p. there is no interpolation. Simply 4 pixels to one.
Now, if you were talking about 1080p compared to a native 1080p monitor, or 1280, or anything that is not 1440p or 720p you might have a point.
Tell that to inhalexhale1, who I quoted. I haven't compared myself, but he's not the only one I've heard stating that non-retina apps (or games) look worse on a retina display than on a non-retina display with 4 times less pixels.
Yes, I have owned both the 1440p iMac and the 5k iMac. Also, I am not saying the 1440p HiDPI mode looks worse than the 1440p native res on the older iMacs. It's way better. I'm saying certain applications are not using a HiDPI mode, and presenting a lowered resolution of 1440p (games typically do this). In that case, it would be the difference of selecting non-HiDPI 1440p versus 1440p HiDPI (or retina mode, as apple calls it) on the iMac. So it's not the screen, but rather how certain applications are handling the HiDPI display. Another example is Native Instruments. A lot of their interfaces look like crap on HiDPI displays (jagged/blurred), but are fine on lower resolution.

Definitely not the only one. Search for it, and you'll find many threads here, on game forums like blizzard, or places like native instruments who refuse to update reaktor, etc.
Clearly, non-retina-aware apps are blurrier than HiDPI apps, but the question is, do they look worse on the 5K than on the 1440p iMac? There is a possible psychological effect here. On the 5K iMac, you can compare a low-res app to the HiDPI desktop, dock, menu bar and other well-behaved apps on the same monitor (unless the low-res app is fullscreen), which you cannot do on the 1440p iMac since everything is low-res. So the difference in sharpness would really pop out on the 5K.
EDIT: one way to test that is to make a screen capture showing a non-retina app. Each pixel should be exactly quadrupled. If it's not (because of some smoothing algorithm), then the app would look better at native (lower) resolution.
Not all applications support HiDPI, and will not look better on your "looks like 1440p" iMac than on a screen with 1440p native. Like I said, look to these forums and others to see evidence of this.
