i start my command to start minecraft with
i have an i7, 8 core processor running at 3.4 GHz, 8 GB Ram
padsp java -Xmx8192M -Xms4096M -jar /home/metulburr/.minecraft/minecraft.jar
I have played around with the amounts of -Xmx8192M -Xms4096M. The only difference i see when using a high number like this is the horizon and distant land loads real fast. My problem though is no matter how low i make this number or how low i set the graphics in the game, i still get 2-3 second lags(in minecraft 1.7.3 and in 1.8. This cannot be a glitch with the new 1.8 version of minecraft but something i need to tweak my system due to my laptop with with 2 core processor at 1.66 GHz, 3 GB Ram can run minecraft better than my big PC. I don't remember how i tweaked my laptop to work it right or tweaked linux to make it work better.
Does anyone have any ideas on how to do this? ( by the way i am using linux mint 11 on both of my PC's)
1) tweaking java
2) making minecraft run more effecient
