Deus Ex: Mankind Divided arrives on SteamOS & Linux on the 3rd of November

Even though my rig is out of a slightest of chance to play this, I will purchase the day it's released just to support Feral!

I wonder how the game perform on linux, because if there is a big gap like on alien isolation it may almost impossible to hit the 40fps average on normal settings, even with a GTX1080 on 1080p... It seeems it is one of the worst port of the century on pc, so unless feral find a way to get better perf on linux, it might be very hard to run the game outside the minimum settings.

Huh? Even on my 970 I haven't had any issues with Alien Isolation, don't remember seeing anyone complain about it either.

Isn't Total War: Warhammer still due this year?

Yes, during the Autumn, so it shouldn't be too far away now. I'd like to raise an Army of Squig's lol.

That's the one I am saving for, but I will pick up Dues Ex sometime soon.

I'll see your Army of Squids & raise you an Orc Warband or two. ;) The Waaargh is coming. :D

A:I Performs fine on my 960 as well. I believe there was a performance bug with Pascal chips and early drivers. You should try again. Sure there's a gap, but nothing that dramatic.

There's going to be a performance decrease compared to Windows. That's just the nature of the porting beast. The best we can hope for is playability. A first person shooter generally needs a steady framerate so you don't get shot during a stutter.

Like many of you, I wonder why Vulkan wasn't on the table. I thought one of the selling points of Vulkan was that it would make porting from DX12 much easier. As of now, we still only have 2 Vulkan games on Linux (unless you count the Android titles). Is there some technical problem with it, or is it just not mature enough?

I was not clear enough. I meant that on alien isolation you loose about 30%/40% perf, maybe even more if you are on AMD compared to windows. So if it is the same with this port, even a GTX970 will barely run on low @ 1080p. On windows, 1080p with a gtx970 you can not reach the 60fps average on normal settings.(between 40 and 50fps)

On ultra 1080p with a GTX970 you only have 30fps max. SO it is the worst port ever made on pc (because they dev it with console on first sight)

I meant if feral port does not perform better than the original, we will all play on minimum settings. Appart for those who have a gtx1080, they may reach 60fps on normal settings @ 1080p. So forget the 2k5 or 4k resolution.

I know graphics are not the most important thing. But I find it disturbing that the game cannot be played with at max settings with a 350€ graphic card, even more that a Titan X(pascal) barely reach 60fps on ultra @1080p. I would expect it to run the game at 4K ultra above 60fps. Nothing to do with feral though.

The DX12 renderer in DXMD isn't really up to snuff. It tends to cause lower performance for most people. Porting the DX11 renderer to an equivalent GL version was probably faster and would still run about as well as could be hoped. Using Metal for Mac was probably a choice due to some necessary extensions not being available and not wanting to increase complexity in the code as the did for Shadow of Mordor (basically faking it with a lot of compute on Mac).

But Jahimself is not wrong. From what I picked up on the steam reviews, the framerates on Windows aren't great. So anything they drop will limit the appeal much more than with other games. And I think Shadow of Mordor did the best in comparison to Windows with dropping about 20%-25%. So even if the DX12 renderer of DXMD is not good, it may still be better than the alternative.

However, I'm not so sure they had enough time to do DX12 to Vulkan yet. However, if Feral has also decided that DX12 to Vulkan is a worthwhile investment, we may see it as a test feature at some point. But in two short weeks we will know exactly how they did.

Actually you can get a great performance on D3DX12 - you just have to implement and optimize it in a proper way. Many D3DX12 games are not in a good shape though. One exampe of a nice implemention is 'Ashes of the Singularity'. The developers also wanted to bring this game to Linux. They also said it's a shame if you spent much work in developing D3DX12 without porting it to Vulkan since the syntax is so very close.
