Here's my own Linux OpenGL vs Vulkan test for Dota 2, not much difference for me

It's okay, different graphical patterns use different features on the GPU. The benchmarks we do can widely differ based on the demos we use, the state of implementation of drivers for a certain GPU architecture etc, driver versions we're using etc.

That all is perfectly okay. All we know now: It's not where we'd like to see Vulkan yet. There is room for improvement in drivers and engines. That's all we can say.

Very interesting. Since for me, well, I used the dem of the guy doing the video, Vulkan clearly outperformed OpenGL. Very interesting.

[edit] ok, on 1080 your test does too :D...

A new benchmark video shows Dota 2 with Vulkan performing better on Windows than Linux

It is. Because it's way better than with OpenGL .. still.

And that there is work ahead for the driver developers - we knew that.

In comparison, they have a lot more experience with this kind of API in Windows bringing it close to DX12 than in Linux. Besides that, we can't consider Linux as the major platform. But we COULD benefit from games adopting Vulkan in Windows, so the real good performance in Windows could in the end help us. And if NVidia and AMD optimize their drivers more, we could get close to the performance. And I'm sure they'll work on that over time.

With the direction of Microsoft pushing services rather than APIs, we could see a change in their stance to DX too one day, as "we don't care what graphics API you use on XBox".. but we're still ages away from that. Though, they have been moving really fast on things like that lately. SQL Server for Linux? C'mon, who expected that?

Hmh, not here. Interesting :-) .. will figure out why :-).

Nuclear Dawn FPS/RTS hybrid updated, some important fixes for Linux included

Ye, didn't play it in ages. Would probably join in.

The cool part was, everywhere I went when I said "I'm a noob and have no clue what I'm doing", they started to help me. Not the typical kiddie game where you only get "f** off you f** noob" or similar. Everyone was friendly, helpful and got me to feel a bit less lost :p.

Quoting: liamdawe
Quoting: STiATyou have to put the file provided into the replay folder, renaming the file to a number.

Then it will show in "downloads" tab at "watch".
Valve specifically gave that commmand I posted above to Phoronix, which seems different to running it inside Dota itself?
It's simply the launch options of dota2

In Steam you can right-click dota2, and select "Set launch options" in the "General" tab.

Note that [-vulkan|-gl] is an OR, so either one or the other into the line (both won't work).

So for Vulkan set the launch options to:
-vulkan +timedemo OctPerf +timedemo_start 46800 +timedemo_end 47000 +cl_showfps 2 +fps_max 0 -novconsole -noassert -nosound

For OpenGL to
-gl +timedemo OctPerf +timedemo_start 46800 +timedemo_end 47000 +cl_showfps 2 +fps_max 0 -novconsole -noassert -nosound

Note that you need the OctPerf demo file in the right folder (I think), which I don't have ;-).
I gathered as much, but doing that acts as if I haven't put any options in. I have the OctPerf file in the replays folder.
For the +timedemo option the .dem file needs to be in the dota folder, not in the dota/replays folder (!).
After that it worked for me.

See https://openbenchmarking.org/innhold/78bee2634b4c092f4978d416ccf6887ddbd1d86e [External Link]

Sorry for the misinformation, the replays folder worked for starting it from in-game ;-).
