In follow up to our previous discussion on graphics developments, there was some news today about upcoming NVidia displays. These are 4K, HDR and 144Hz that got announced in Jan 2017 and were supposed to ship last year, but are now expected to ship 'mid year' in 2018. These were badly delayed, either because of the updated GSynch tech needing work, or the panels needing work. This is significant because there are several non-HDR 1440p high refresh panels now available that currently define the 'sweet spot' of monitors that current graphics cards stand a chance of powering. Even a 1080Ti would not be able to drive these 4K HDR screens at 144Hz. In theory, the graphics card is technically capable of the resolution+HDR but not at the desired framerate. I'm not aware if there are also FreeSynch2 versions of the Acer/Asus monitors at this level (if not, could imply that the panels were the source of delay). Reason I post this: there's been no mention by S397 of support for true HDR (10-bit color). While very uncommon now, I can see it becoming much more popular in 2-3 years, because most 4K TVs already ship with this capability albeit the panels are not true 10-bit capability and below 3-400 nits brightness. This will come across to PC monitors when the graphics cards can drive this at 60Hz or better, and I think we will soon start to see cheaper low-end 4K+HDR monitors based on the TV tech and those might become the defacto baseline. [There are non-HDR 4K 60Hz monitors now, and since no-one is making/buying 1440p TVs, I think that'll get skipped]. If S397 have a 2-3 year 'capability development timeline', then its getting close to being required. PC2 software is apparently capable of HDR and can support 8K and 12K displays, though of course, these don't really exist and probably won't for the life of that title. I'm of the belief that HDR will be a game-changer in terms of graphics realism, moreso than more pixels. S397 have to support good performance at 4K on mid-to-high end cards, but I'd like to see that be 4K+HDR performance. I'd also note that DX11 was released in 2009; DX12 was released in 2015. Doubtless DX11 still has a long life ahead of it, and I'm sure S397 think they are only just starting to leverage what it can do. UE4 was released in 2014; I think it now supports DX12. In a couple of years pretty much everyone will be on Win 10 and have DX12-capable hardware and we'll have the first UE4 games from Kunos and maybe Sector3/Simbin; and I'd expect PC3 to use DX12. S397 won't want to port to DX12 having just done a port to DX11, within the next few years, but they may well need to start planning for it if they intend to support this title beyond 5 years. S397 did a pretty swift transition rather than maintaining code 'in parallel', something iRacing did for about 18 months and I'm sure they'll take the same approach next time.
