I got an R9 Fury the day after launch with the intention of being able to max out basically every game at 1080p but I'm getting really poor performance in most games and I'm not sure why. Dying Light I average around 20 FPS on the Performance preset. Ark Survival I average around 40 FPS on the Medium preset with Epic render distance(actually improves FPS). And there are others where my performance is console grade or worse. I have the latest 15.7 drivers from AMD and I'm running the 3.19 kernel. In synthetic benchmarks like Unigine Heaven and Valley I get scores of 1187 and 2404 respectively while they were on the highest possible settings with Ultra quality 8xAA and in Heaven Extreme Tessellation so I don't think it's a driver issue but it may be. Can anyone offer any assistance?

Note: I'm pretty sure it's not a CPU bottleneck. I have an FX-9590 and according to my hardware monitor on my secondary display my GPU is generally pinned at around 100% use during play.

could be ? you see a lot of that these days ?? like I said its a new card and theres bugs to work out .. rome was not built in a day . like I said to look at all the card/game issues just for windows ?? so all you can hope for is a better optimized driver in the next release ?? [no matter card ]

my 7850 I still use 13,12 driver for it them 14.xx drivers to me don't seem as good in a few areas so I keep going back to it ?

I found this https://www.gamingonlinux.com/articles/dying-light-is-almost-playable-on-linux-if-you-do-some-tinkering-updated.4899 so I'm going to try that.

Well I'm hoping Vulkan also gives Linux a boost or if nothing else better performance. Also I tried it. It does increase performance but it swings anywhere from 30-60 and I still don't get great play but it's so much better than it was.

you know I think you can still get the etqw demo and run it and see how well it does ?/

http://www.splashdamage.com/content/enemy-territory-quake-wars-demo-linux

its a good map and action - the game is capped to 60fps but you should tell by the game play and quality - to me its one of the better gasmes on Linux

cant hurt to try it out ?? I guess it will still work with the newer kernals ?? like I said I got the full game on retail disk so its not a issue ???

Yea I might give it a run. Also I have another weird issue and since you're familiar with AMD on linux I was wondering if you've come across it or know how to deal with it. Sometimes I'll get weird artifacting and horrendous screen tearing in games running on the Unity engine and if I reboot my system it'll go away generally until the next day or next cold boot. I would think it's the card but like I said it only happens in Unity games and since a reboot fixes it I'm assuming it might be a driver thing.

that's hard to say ? really could be anything ? or the game ? I guess you still got you old card ? maybe swap them out and see ? bad thing is a older or different driver may not support the new card to be able to try that ?? things like that is what I seem to somethims get with all the windows 14.xx drivers and end up going back to the 13.12 that I don't seem to have issues with like the 14.12 driver can causes a blackscreen at times and blurry text all the time s it uninstall it and reinstall 13.12 it does all my needs with out issue ..

like with all new just released stuff you get your the Guiney pig .. all yuou can assume is it just need a driver hot fix or updated ??

theres a updated part to that bench review from yesterday

https://www.phoronix.com/scan.php?page=news_item&px=Radeon-R9-Fury-More-Tests

over in comments where one guy said he changed the file name and improver performance a lot ??? [8th one down by dungeon ]

Alright well it just seems to be the Unity engine which I find weird but thanks for the advice. I do still have my old card so maybe I'll give it a swap.

Also here's something interesting. http://support.amd.com/en-us/download/desktop?os=Linux+x86 if you go to the supported products tab the Fury isn't technically supported by the driver. If you compare that to the Windows section you'll notice instead of specifying Fury X they say Fury Series. I wonder if that's just a mistake or intentional. Especially since windows is on 15.7.1 where linux is just on 15.7. It might be that the .1 is adding Fury support but I'm just throwing out theories at this point for why it might be so under performing outside the fact that AMD has bad drivers.

thing is weather its windows Linux what ever all these company's seem to do is hype up a new item to sell weather or not its got any support or compatibility .. its just hurry up and sell and we will worry about the rest later when we get the time .. I'm sure you see that trend in all this hardware these days ..

I sure by the next driver things will shape up some or make something worse trying to fix something else ?? all you can do now is hope and see ..

Yea no kidding. I'm really disappointed with AMD. They need to get their shit together. As it is I just bought shadow of mordor yesterday at launch and can't even run it because the dev said "no AMD support on Linux because of poor drivers" and I tried anyway but it crashed. Phoronix didn't crash but they got horrible artifacting. I'm just disappointed.

well as I now learned its best to do hard research on these parts these days all guys see is the hype and blinded to the rest of the story -- lot of junk out there ..

heres one more thing with amd notice they don't support anything under windows 7 - then look at there higher end cards no on card analog support [dvi-I or vga d-sub ports ] nivida does all ther cards have a dvi-I see I still run a lot of old software [xp & vista ] and hardware that amd no longer supports - NVidia still will
I cant see paying them prices on a card that cant run all my software or on all my os's $500-800 for a card that cant do 1/2 of what this old $175 7850 can do out of the box?? wow

then I go to there archived driver page and most of the old driver download pages are broke or don't work ? so amd seems to have tossed aside guys like me and has gotten real proprietary on how and what ''they' feel .. like I said just keep shooting them selves in the foot and can understand why no one wants to use there stuff and loosing money??

lucky for me I save all good old drivers in my records

Yea the lack of DVI-D support threw me. My secondary monitor is a really old Dell 1280x1024 5:4 monitor that uses VGA or DVI-D as input and so I'm using HDMI to DVI-D since they're electrically compatible so I don't need an active converter but I know what you mean.

I see you got the asus card ?? seems the only one that has something other then hdmi and displayport ? at least the only one I see at egg? [did not know that on any fury ]

http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100007709 600566291 600566292

looks like asus tried to look out for things adding that to there card. interesting ... but still no anlog support unless you ''buy'' an active converter adaptor [$25]

No I have the sapphire one. I'm using hdmi to DVI-D to connect my second monitor and DP for my primary. I didn't know Asus had one with native DVI-D.

Honestly I partially want to dual boot Windows 7 because I spent $550 and don't get anywhere close to the performance I wanted but at the same time I don't know if I could tolerate it and then once AMD drops Win 7 support where do I go. I have no interest in MS collecting all of my data in Win 10 and I don't want to run Win 8.1 so I'm back to Linux. God dammit why is Linux support so bad 🙁. It's the best OS out there yet AMD doesn't care about us 🙁.

I think it has less to do with it being free but rather only like 1.8% of all PCs run it. Either way I wish AMD support for it was better. I can deal with the lack of titles and all of that stuff. If I couldn't I would have just stayed on windows. What is frustrating is poor performance on those titles because AMD has a crap OpenGL driver.

well its a Microsoft thing cause strong armed everyone in to direct x I was looking for a article that covered opengl and direct x and found it interesting and it seemed open gl was the better way but it just wasn't Microsoft and they could not capitalize on it as they do dx so they said we wount support it on there os and got there way on that.. its all about control and money - the Microsoft way

this one is not a bad read?

Yea no kidding. That's a real big disappointment. Unfortunately the OpenGL drivers aren't as good so even if OpenGL is better because of inefficient drivers it performs worse.

well ther going to kiss microsofts a$$ first and foremost .. that's just life .. and now with that crap 10 coming out and with the new dx12 that will put Linux support on the back burner once more until that gets caught up .. then you take AMD in there situation they probably let go most of the staff they had that worked on drivers and are short handed in that department ?

look how hard it is to get a fresh working driver that optimized for a hot new released game to start with ?? they can hardly keep up for the Microsoft stuff as it is now [NVidia or amd ]

I'm hoping vulkan boosts performance but that all depends on if AMD has a decent vulkan driver. I'm hoping they will.

I don't install anything either. If you're not familiar with what Vulkan is it's the OpenGL replacement/DX12 competitor being released by the Khronos Group this fall.
