Underpowered GPU and VR Headset

I have a laptop with a Nvidia 2060 RTX Mobile GPU. I know that it is not powerful enough to run the HP Reverb at full refresh and full resolution for, pretty much, any game. However, I don't intend to do too much gaming, more watching movies and looking at images - that kind of thing. So, will the Reverb run, at all, on my computer, and would I get the full effect from it for things like watching movies or looking at images? How poorly would it perform for other things (games)? I'm looking between this and the Odyssey+ and trying to find the all around best visual experience; I'm fine with the Reverb if it will provide a better one, even if only situationally, but I'm not sure if the lack of GPU power might make it perform worse in some situations. In general, I have no good reference point for VR stuff, no real way to try them, and am looking to get the absolute best experience I can get, any help (specific or general) would be greatly appreciated, thanks in advance:-)24.3.61.185 (talk) 08:07, 5 July 2019 (UTC)

Just a general comment, you don't want a slow refresh rate on your VR headset. This causes disorientation and nausea, if when you turn your head the image doesn't move accordingly. Better to just use a normal screen than risk that. Or spend a lot of bucks to get the VR headset to work quickly. Your choice. SinisterLefty (talk) 17:04, 5 July 2019 (UTC)

If that's all you are going to use it for, you might want to consider an Oculus Go. It doesn't require a computer at all, and is a lot cheaper. It seems a waste to pay for expensive hardware and then use it with a computer that severely limits that hardware's performance. CodeTalker (talk) 18:20, 6 July 2019 (UTC)

I can definitely run the Odyssey+, which should give a better experience than the Go. But, it isn't clear to me that the Reverb would run at a reduced resolution for videos - for games, I'm not sure if downsampling enough to hit a decent refresh rate will lower picture quality past something I run without downsampling. It's sort of like being able to run things at 2k resolution but having to choose between a 1080 and an 8k screen, it isn't obvious that the 8k image will be better is rendered at a reduced a resolution (that's a rough comparison of course). I wish there was a way to this on a trial basis, I don't think there is an easy answer of out just trying them. Maybe I'll just buy both. — Preceding unsigned comment added by 24.3.61.185 (talk) 00:28, 7 July 2019 (UTC)

For your example, it should be better on the 8k screen, unless it has to also drop frames due to the downsampling taking up processing time. At worst it should appear as a 2k image, but if it does a decent job of interpolation, it might appear somewhere between 2k and 8k. SinisterLefty (talk) 03:01, 7 July 2019 (UTC)

MediaWiki ordering of Chinese characters

I just ran across Category:Disambiguation pages with Chinese character titles and was surprised that each initial character has its own section (as if each one began with a distinct ASCII character), rather than all being grouped under a single section for Chinese characters. Do we know how MediaWiki collates them? I asked a related question at Wikipedia:Reference desk/Archives/Computing/2017 December 14, but that was about Excel and "other programs", not particularly MediaWiki.

I suspect they are ordered in the same sequence as in Unicode. This sequence is also the standard ordering in a dictionary. This is ordered by the number of strokes in the radical. Then within that number there is a standard sequence of radicals. For each radical the characters that contained it are ordered by the number or strokes. However there are extra complexities in Unicode and media wiki, eg see Han unification. Graeme Bartlett (talk) 23:10, 5 July 2019 (UTC)

This isn't really a RD/C matter - it's more for WP:HD or if they don't know, WP:VPT. --Redrose64 🌹 (talk) 16:27, 6 July 2019 (UTC)
