NVIDIA vs. AMD Linux Performance For GRID Autosport

[dungeon]

You are making wrong conclusions again. You are comparing completely two different graphics engines there. A well tested and optimized DirectX based one, and an OpenGL based one made by third parties for the less than ~%5 of their user base.

So roughly speaking this OpenGL based port made by third parties performance is about 70% on average compared to the well tested official DirectX version, and that is on nVidia hardware and nVidia drivers of course.

And how is that wrong conclusion, percentage is average 70% there which is nowhere near the same as on Windows... does not matter how much something is tested or not. You pick both versions and compare that is all.

Yes i am aware of that optimistic words, if difference was 5-10% one can swalow that but really those 30% missing (that percentage is in area of CPU and GPU hardware gen difference!) in the best case for some Windows user wanted to play on Linux... is in the range "be or not to be" or he can easely comment "how AMD driver is disaster, when nVidia is disaster already"

I think recently Ars spread away whole truth about gaming on SteamOS and Linux but also about nVidia Linux nonsense performance fame, perfromance adventage has been non existant whoever game they picked up to try - even those from Valve which are considered fine ports. Results were quite opossite even on those and in 99% cases by definition slower, etc....

Yup, meanwhile you die hard AMD fans can continue waiting or write drivers instead of AMD, while PS4, XBox One and workstation users are enjoying the long term and quality support with your money

You separete there unseparatible, because I already have Playstation 4... how you write this i would think it is blasphemy to be Linux user and to have PS4

Believe what you want, it won't change the fact that nvidia almost always offers about the same performance as it does on windows.

Those are optimistic words (pesimistic should be 'almost never') i heard for decade plus, but reality is different (reality is something neither optimistic nor pesimistic, but how it is). Nvidia does not automagically deliver same performance, i know Linux people for years talks about that like it is holly something but it is BS most of the time ... as a proof another video here for this Grid game with nVidia hardware - he have 60% to 80% performance depending on settings:

So roughly speaking this port has performance 70% on average and that with nVidia hardware and nVidia drivers of course.

Also i am sure that AMD can make 60% on average once this game is profiled, but all this does not change fact that those ports are slower on Linux

Looks like a quality racing game, too bad it's not need for speed (I enjoy the cop chasings) or flatout (I enjoy the destruction), but for pure racing fans I'm sure this is fantastic!

Ok, now I understand.

Yeah, quoting what you want and cut what you want, means to me you want to joke around

Believe what you want, it won't change the fact that nvidia almost always offers about the same performance as it does on windows while fglrx trails Windows by a large margin. If it's not because of bug, then maybe it's because of features?

But same thing is with Catalyst on Windows and Linux, and OpenGL Windows and Linux. AMD provide about same performance on Windows and Linux... but for most performance on particular titles they made and run profiles - both Direct3D and OpenGL games under Windows have performance and other Catalyst profiles

By that definition, if you don't run Cat profile on some Windows game and then say that is disaster, means to me that you just want to joke around And If particular game currently does not have profile, that also does not make driver disaster it just means that when it come to top notch performance catalyst is per app driver - remember that

Once again, AMD OpenGL is exact the same on Windows and Linux... minus some profiles here and there might differ or miss, minus platform specific features.... and hard fact that Windows/Linux games are not exactly the same, just nearly the same and when it cames to perfromance those can suffer from indirect factors too, etc...

Fglrx is not subpar driver, but it is...

Ok, now I understand.

Ask Feral how much bugs they hit with nvidia driver, probably same amount as with AMD and Intel It actually depends how much you work with one or another

Life is so much easier when you think the world in your head...
MoonMoon has shown you Feral tries to work on nvidia, amd and intel at the same time. If they have to ship something that only runs on nvidia, surely it's not because fglrx is working just fine (which is where our discussion started). It's because fglrx is a subpar driver.

Fglrx is not subpar driver, but it is because drivers are different... and why drivers are different? because different people wriote them, and because well hardware is different... and of course they all might have bugs.

Ask Feral how much bugs they hit with nvidia driver, probably same amount as with AMD and Intel It actually depends how much you work with one or another

But we talked by performance primarly, which is a thing which can be also be platform specific. See there, same man, same hardware, same nvidia driver version, two SteamOS versions and different performance... so on OS upgrade perf goes down

So it is not a driver there as a problem, it is something else, some indirect factor So Catalyst CPU cap issue might even be as suffering from some glibc miss optimization issue on XYZ distro, but not on another further it might be while it works on nVidia it broke all others - if they use different compiler to made their blob, etc...

So what do you think on video, does SteamOS 2 should fix their nvidia driver issue or what else No, nvidia driver isn't perfect as you might think

[bug77]

Issue is non existent in my mind...

Pascal going to need that HBM2 to soft render that async and still be slower, who wants to make a bet that NVidia next gen will false advertise async compute? lol!

So where i lied? I was asked and talked about performance here. This port version is CPU capped too on nVidia, i expect nvidia should fired up this results further... if platform is Windows but it isn't

[MoonMoon]

Issue is non existent in my mind, as even Feral for all their ported linux games stated Intel and AMD GPUs as unsupported . They develop it on nVidia hardware for Mac then Linux at first, once that pass on XYZ nvidia driver version that seems enough for them to release game....
