How about a link to this article.
I think he's using Doom (final) im Benchmark-Test: Schaurig-schöner Splatterspaß - Benchmark-Ticker läuft, but if you go by the thread at DOOM (2016) first benchmark review | [H]ard|Forum which also links to the article, one of the posts says that DOOM is actually not using Vulkan, but just a Vuklan wrapper, so it may be some time before we get to see what performance shakes out to be. Not surprising, game developers are always rushing to cash in on hype, releasing unfinished products because plenty of kids eagerly pony up for a buggy game and because they know the bulk of the complaints will unfairly be directed to AMD and nVidia instead of to them.
Thanks, i'll have a read.
Haven't got the game yet (give it a month or so).
I can vouch that performance in DOOM is totally unacceptable on my R9 290's (Hawaii) in single card configuration and Crossfire support is totally non-existent. Like Kingfish said, file a bug report AMD Issue Reporting Form and hope that a hotfix driver is incoming shortly. There's definitely something not right about this.
In my test results below, you'll see that non of the results make any sense.
Graphics Settings Tested: Ultra, High, Medium and Low
Results Displayed Below: Ultra
Maximum Frames Per Second: 97
Average Frames Per Second: 47
Minimum Frames Per Second: 12
Regardless of settings applied, I received nearly the same frame per second results throughout each test. So hopefully something is done soon in regards to stabilizing performance.
