Default Re: Why are Linux (graphics) drivers slower than windows drivers??

The Windows drivers overoptimize on a per game basis too remember. They cut corners whenever they can. Loads of game specific code in them. We don't get that "advantage", and in fact I'm glad about that.

Anything for higher benchmark scores on big name review sites.

Too stop this silly thread, Windows is a closed source 'secret squirrel' OS - you can make the bench mark tests prove any result you want - you have no control on what it measures, nor on what the bench marking tool reports, as it is all hidden.

You cannot compare oranges and apples.

Now, that's a silly argument!!

So according to you, every windows based benchmark out there is "fake" numbers, produced by the OS. As long as the output is reasonably the same image quality wise, I don't care what one OS does to get better performance than the other one.

You cannot prove that Windows benchmarks are not contrived (how can you?).

A lot of things are hidden and mis-reported in MS software (i.e. transfer of data over TCP/IP) as they remove/absorb the overheads that they considered the user doesn't need to see.

So comparing MS windows with any open source OS is a false comparison.

not so fast!

nvidia cheated... you see why _we_ are sceptical about windows benchmark.

Yes, there have been issues.

But in most cases optimizing (not faking higher scores) is only for the benefit for us users. Per game optimizing is brilliant in my opinion. That way we get the most from each game. This is as long as it's not affecting image quality in a noticable way of course.

Here are some NVIDIA Windows Versus Linux Numbers from last December:

Here's another one:
http://www.linuxhardware.org/article.../10/12/1725246

Of course this is not enough to base a conclusion, but it gives a hint of the general performance.
This is not a "Linux sucks" thread, I'm genuinely interested in why there are such differences in performance when the drivers are almost the same
and you can read what ID said when they released doom3? It is optimized for windows, and all assembly optimizations are currently windows only. As more patches showed up moving more optimizations into the linux port the gap closed.

It's the same with most native games, they are far more optimized for windows, and linux still wins over windows in some benchmarks (especially after a few simple optimizations patches).

If I can remember correctly I tried that.. but that turns off accel in x doesn't it??

The problem was that I couldn't get rid of mouse accel in Q3 even though I could remove it in X. It's a known problem, and there are some solutions to it, something about adding a "fake mouse" in a config file, fooling q3 to set mouse accel on the fake mouse or something. Anyway, it wasn't easy..

Ok, so it's often not the graphics drivers that is the problem (but linux drivers still lack in features compared to windows ones), but rather bad linux implementations even with the native games?

Default Re: Why are Linux (graphics) drivers slower than windows drivers??

If you look for speedy Linux try source based Linux distro (lunar-linux, source mage, sorcerer, gentoo, rock...etc) build it for your CPU with all mmx,3dnow,sse123 support, all gcc optimizations enabled and minimal number of appliactions installed. I think this time Linux will win the race with speed and quality better than in all windows games. The popular Linux distros are slow because are binary optimized for generic Pentium (586). Later distros moved to 686 but this is still much slower than fine tuned source based distros.

Then ask Mr. Bill Gates for source based Windows and do the same to have similar testing environment.

Optimized Windows games and drivers break quality and compability. The screens are ugly. Many reviews described such cheap cheats.

look at Microsoft servers (after coming in (pirate) )
