NVIDIA/Radeon Windows 10 vs. Ubuntu Linux Relative Gaming Performance

This is a great comparison. This is very useful for people to decide, whether they would be able to switch to Linux or not.

Not to sound like a troll but these choices in benchmarks are actually quite damaging for this reason. Most (not all) of the games benchmarked are using D3D to OpenGL wrappers and aren't true ports (All Feral releases). They don't give a acurate perspective of performance based off the platform. Native ports such as Metro, DOTA2, CS:GO, Stellaris (this list goes on) are better choices. I feel this should at least be mentioned in the article.

This video shows it even better, so conclusion is obviosly not the same... most noticable is that people moving randomly and different

There are no differences between Windows and SteamOS, but rather between benchmark runs. Rarely benchmarks are identical in every detail, most of the time are more like scenarios where a certain amount of actions are taking place at random.

That being said, it gets me to wonder - what if Linux may be doing something wrong (besides the obvious outdated parts of X11)? If both AMD and Nvidia hardware suffer roughly the same performance losses, in one perspective, you could say that there is something Linux does less efficiently that the drivers cannot compensate for.

amd and nvidia suffer roughly same wins in non-shitty ports like metro or openarena. nothing is wrong with linux, problem is with directx renderers wrapped into opengl without redesign. also both linux drivers have no application profiles

[pal666]

Especially NVIDIA should deliver similar driver blobs to both platforms.

it is similar but directx and opengl are different drivers. and also it does not have app profiles

It's the scheduler. Here's how Windows and Linux handle thread scheduling:

you have some fantasies about scheduling

[pal666]

This is one of the reasons why I prefer to play games on Linux, latency seems much better.

i'm with you when you prefer to play games on linux, but that fantasy is not reason for that. btw, "better latency" is the definition of "the highest priority threads ALWAYS run" lol

I'm a little surprised to notice that Windows, while it has a higher framerate, has texture loading issues the Linux version is avoiding. If you watch the video, you'll see that sometimes Linux will have the high quality textures loaded one or even two entire seconds faster before the textures on Windows are in.

nothing surprising here. windows has orders of magnitude slower filesystem

[pal666]

OpenGL does have some bigger overhead than DirectX has. That's not a new fact.

it doesn't have bigger overhead. it just requires different design. which requires manhours when you start with directx renderer

[pal666]

Everything is 100% up to game devs to make sure it is running flawlessly, right?

of course. it is crazy to think otherwise

[pal666]

Sometimes DirectX's integration with Windows offers it a performance enhancement too.

there is no such thing as directx integration with windows. linux videodrivers have kernel counterparts designed for maximum speed of opengl user level driver. you can't get more integrated than that

In order for poor porting to definitively be the blame, the percentage loss of performance should be a lot more variable.

more variable than from several times slower on linux to slightly faster on linux? why do you need more variance?
