Minecraft low FPS help

[Adrian719]

Hey guys,
Well I switched to F15 over 10 days ago. I was using WinXP prior.
I play minecraft all the time, and I also do "lets plays". My average FPS used to be 60+, now I'm down too 3FPS on average.

My system specs are not the best, but I know minecraft should run fine, since it did on XP.
Now my question is, are there any unecessary programs or processes that I can close? Or is there anything else I can do (besides from buying another computer LOL).

thanks guys!

I noticed in another thread someone had said that the fps in their games dropped considerably by using F15 compared to F14.
I had suggested using a seperate X server so the graphics chip is not rendering the desktop and game at the same time. There was no response so I am not sure if ti helped or not< but...

In theory you would just have to type.

xinit /usr/bin/nexuiz-glx -- :1

In the above example just change the path to the minecraft excutable. This should start a second X server and only render what is on screen. Your desktop would no longer be rendered at the same time in the background with the game. ctrl+alt+F2 or the proper corresponding F(#) should allow you to flip back to your desktop and gaming desktop while the game is running.

If this improves or greatly improves the performance we then know it is the graphical rendering of the desktop that is effecting the games so much. If not we need to look at something else that might be causing it.

Okay cool. I will read up on that and try it out.
BTW, the process "Npviewer.bin" is using 50-60% of my CPU on average. I think that is affecting it also.

Uh it seems as though putting "xinit /usr/bin/javaw -- :1"has royaly screwed up my font lol.

Npviewer.bin is ( Netscape plugin viewer ).
This forum posting from Suse seems relevant.

I would go so far and say before loading up the game do a killall -9 Npviewer.bin to make sure the process is not running. Mind you this may effect flash or other plugins currently working in your browser.
I also assume minecraft is a java based game? It doesnt require the browser does it? If it does this would explain the high cpu usage and I would think this would be normal then.

As for the fonts, I really don't know what to say. Starting another X session really shouldn't effect that.

Maybe something has drastically changed in the xorg server or in gnome 3 that I am unaware of.

I have killed the process before, and it only affected flash in my browsers.
Minecraft does not use internet, but it is a Java program. Javaw opens and uses alot of RAM.
I'll try killing npviewer.bin when I am going to play minecraft, and see if it does anything.

NPviewer seems to be closing now when my broswer is closed. Before, it did not do that.
Minecraft is running okay, but still lags. Also, I can not change the priority of javaw.
