This is your once a month reminder to make sure your PC information is correct on your user profiles. A fresh batch of statistics is generated on the 1st of each month.
You need to be logged in to see when you last updated your PC info!
You can see the statistics any time on this page.
While we don't currently have a drop-off implemented for old/stale data, it will be implemented next year. If you want to make sure you're included at any time, clicking update without any changes will update the last time you edited them. The drop-off for old data will be done in months, since people aren't likely to change hardware that often.
Some you may have missed, popular articles from the last month:
One of the reasons they do it is DRM garbage as far as I understand (HDCP).
All of them are bad ports. I.e. they are doing some weird stuff with OpenGL, so if developers don't want to fix them - skip those games, or if there are workarounds - apply them. Such games suffer from the fact that developers didn't test them with Mesa. This issue should be non existent for newer games.
They should be soon, from Linux 4.15 and on. AMD were actually working on upstreaming it all, unlike Nvidia who don't care. So it will all "just work", using out of the box kernel.

Another annoying things in amd drivers (good point)
Without forget dont have complete opengl extensions (them stay close to 4.6 but need conformant test once time lack extensions stay ready)
AZDO extensions have serious retrace, in last 6 months dont advance much (in this time them must be have all AZDO extensions complete with conformant tests)
Compatibility is another big issue in amd drivers
Bugs in various titles native and non native
For now nvidia is "just works" driver for most apps native and non native
Hopefully amd them can improve in 2018 for have better options
But in hardware side them lack of tdp / performance gpu, maybe if navi appears using 7nm can show interesting product

Ironically, Nvidia made some of the best AMD motherboard chipsets (nForce).
When i had a "green" card, it used to crash my whole system (with their driver, not the noveau one). I don't want performance, if it comes with frequent system crashes.
As for the games, it's mostly the fault of the developers. I had some problems with Mesa, mostly with older feral ports that supported the non-free driver (shadwen/trine 3) but those went away since.
Vulkan is a very new API, i doubt that most devs even know yet how to do things well in it, also, as far as drivers are concerned, since they opened up their code base, nobody will want to do the work twice, so most likely one of them will die out, or they merge in time, but i wager it doesn't go overnight with complex code.
amd is getting better and better but still not there sadly, still many games that dont work, hdmi audio doesn't work etc, yeah yeah 4.15 will fix hdmi audio and stuff but its not stable kernel yet.
since i own GTX 1070, i have nowhere to upgrade really with the ~500€ GPU budget range. vega 56 is pretty much same in terms of performance if the drivers work and only now some of the non-ref cooler cards started to appear, which is a bit late to the party, GTX 1070 is more than a year old and all AMD achieved was similar performance on the same price range 1 year later than nvidia.
hoping to see what the next year brings with volta and vega2?

Good points too
In my case nvidia works ok (native and non native apps) with ubuntu stable kernel, manual installation
DAL code is a big step in amd drivers (thankfully torvalds approve code) but need stay in stable branch thinking in ubuntu 18.04 LTS launch around Q2 2018
Amd have serious troubles in hardware, as your said vega appears 1 year later with similar performance than pascal but pascal stay since 2016
Vega consume so much for example vega 56 around 210w at stock clock meanwhile GTX 1070 consume 150w at stock clock
Curiously amd invest in hbm for improve consume but in practice consume more than actual nvidia gpus
Amd needs create very good gpu core, improve actual tdp and other things
However with titan v launch seems nvidia dont give to amd any chance of recover
Volta is impressive how much improve in same consume of titan Xp (250w) with much more shaders and others
Without forget using 12nm, and nvidia now have ampere as volta succesor
If volta desktop based cards appears in H1 of 2018 (possible using samsung ddr6), amd stay in serious troubles in hardware side
^_^
I have one of them some years ago with athlon xp 2600+ barton core*, audio chipset (depending manufacturer) will be impressive in this time
*In this times 512kb of L2 are impressive

Nvidia doesn't "just work", devs keep working around their terrible shoddiness because Nvidia users keep crying foul if stuff doesn't work properly for them.
When something doesn't work properly on AMD it's AMD's fault, when something doesn't work properly on Nvidia it's the project's fault. Nvidia users are like Apple fanboys who keep deluding themselves so as not to have to face the reality that they've got serious Stockholm Syndrome.
