So, I'm entering the world of Linux (Xubuntu 12.04) and I've got almost everything 100% configured...

The only thing that I can't solve now is this mumble-overlay issue...
when I run ezQuake without mumble-overlay, I get like 1500, 2000 fps...
and with mumble-overlay, I get 500, 300, 700 at most...

These are my settings:

(I have 2 executables)
start_quake.sh
ezQuake_World_-_85hz.sh
______________________________________
start_quake.sh

xinit /home/kernell/Quake/ezQuake_World_-_85hz.sh -- :1 vt8 -config quake.conf

please help!

I think a performance penalty is expected here. The render pipeline gets more complex if you blend over something into something else. Similar reason why you should see better performance when running in full screen compared to a windowed mode (not sure if that applies to X11 as I'm not sure if there is such a concept as full screen - I thought everything is just a window here even if it covers the whole screen). How good this is handled is probably up to the window manager or graphics driver.

Your system specs are missing from this post so no idea if it can be improved. There is a similar thread in the advanced configuration are where performance on Linux in discussed - especially using the OSS drivers.

Thanks for the help Tuna, I think there should be a performance penalty also, but not this much.. like, from 1500/2000 FPS to 250/500...

I tried lots of stuff, but even starting ezquake in the standard X (without the "xinit" command) I'm getting the same fps...

(thanks anyway, i'm gonna read more in other threads later)

btw:
Notebook: ASUS G73SW-BST6, nvidia 460m, 8g ram, Core i7, everything TOPNUTCH...
my cousin bought it for me in the USA...

ok, oddly, my fps changed all of a sudden... now i'm getting normal fps... (little bit lower, but normal)

thanks anyway!

now i'm have only one doubt, why using in_mouse 3, I only get mouse-rate maxium equal to FPS?

I used to set cl_maxfps 510 (to match my 85hertz external CRT display, to be smooth)
but then, when I check with m_showrate 1, my mouse only gets 510 rate...)

i think this is coused by the in_mouse 3...

now I play with 700, 900, 1200 fps, and my mouse rate is varying with these values...

I would like to play with cl_maxfps 510, and mouse rate 1000 hertz...

The problem is with your kernel. Download kernel source code and open kernel/signal.c using your favourite text editor. Go to the line 214 and replace
static DEFINE_RATELIMIT_STATE(ratelimit_state, 5 * HZ, 10);
with
static DEFINE_RATELIMIT_STATE(ratelimit_state, 5 * HZ, sig);

then make && install new kernel. Finally enjoy proper mouse-rate behaviour.

Can't really say much about it. I don't even know how this is calculated in EZQuake. Since its single threaded I would assume mouse positions are evaluated once per frame. How many updated from the USB bus have been send though might be totally different.

perfect awnser!!! I'm feeling so good with ezQuake in xubuntu, that i don't care anymore, it's much more smooth than Windows 7...

PERFECT NOW!!!!!
thanks!
