 Posted: Sat Mar 17, 2012 8:56 am Post subject: 60 FPS? Is this bad? |
 |
|
Hello all,
On running glxgears it says I'm only getting 60.000 FPS. I was reading this website, http://www.cyberciti.biz/faq/linux-test-my-graphical-performance and it was indicating I should be seeing 6000.000
My system is 8GB RAM on an Intel i7 2600K using the inbuilt graphics.
The only reason I'm looking into this is I was running some games for my son (Trigger Rally,etc) and they seemed sluggish compared to my old Pentium 4 box with an NVIDIA 6800 card.
Thanks

| Code: | Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate. |
do you understand?
use | Code: | | vblank_mode=1 glxgears |

to make megabaks comment more readable: You will always get 60fps regardless of graphics power if the output is synced to vertical refresh, i.e. one frame for every refresh of your output device (if your monitor had a different refresh rate this would be shown)
so you can disable this behaviour with the code megabaks posted

| Glxgears is not a benchmark. The number is spits out is meaningless. No "if"s or "but"s about it. It's meaningless. The scene it draws is so simple, it has nothing whatsoever to do with *actual* 3d usage. |

does your card have an opengl interface at all?
Also are there different drivers from the default x11 ones for your card too?
if you do an "eselect opengl list" what options do you get ?

Using the revised command suggested by megabaks and clarified by maltinator - I'm getting figures in the 5548.392 region thanks
Splink please see below
| Code: | Available OpenGL implementations:
[1] xorg-x11 * |
From what I can tell all seems OK, but maybe I need to find a true benchmark

ahhh ok.
That means that you are using the standard x11 interface so your card for glx gears will only render it at a certain speed. I have a nvidia card here and I can use the nvidia opengl interface and I get the following:
| Code: | | 24640 frames in 5.0 seconds = 4927.898 FPS |
But as said, glxgears is not a direct reference to FPS at all, however the x11 drivers will not render as fast as a custom interface which is using a driver which access the opengl stack. A good way to find out what implementation of opengl you are using and what commands are supported by the driver is to just do

As you can see there are a lot of custom Nvidia supported functions which come from the installed NVidia drivers. I am guessing that your card will just use the standard x11 implementation because there may not be an opengl implementation of your card drivers for x11 outside of the normal driver pack.
What I would do is do an lspci, find out your model of your card, goto the website, see if there is any external driver which does support opengl and the glx interface and install that if possible. Outside of nvidia and ATI, I dont know really if anything is supported - especially the standard intel 915 chipset.
Of course, if you are not going to be doing a lot of opengl stuff on your machine then dont bother
