Java games rock!


« Posted 2004-09-14 14:12:42 »

I am a big fan of Java games but have found recently that many of the "action" type games that I used to play run extremely fast on my new computer.  Is there a way to externally control how fast a java program will run?  

I have a 2 ghz Pentium 4 running Windows XP.

If there is a better place to post this question, please let me know.

Thanks,

Drakkett

If your using Internet Explorer and the microsft vm then you can turn off the jit compiler. There is a check box under Tools->Internet Options->Advanced->Microsft VM->JIT compiler for ...

I tried changing the JIT option and it does not seem to have any affect on how fast the games run.

Did you restart the vm? To be completely sure, try rebooting after clearing the jit checkbox.

Depending on the game, it might still run to fast. Do you have a link to a game?

This is a general problem with badly-written games not limited to java. You should be able to find a wide variety of "slow mode" programs that will make an arbitrary application run slower; it's been so long since I used them (in windows NT) I can't remember any names Sad.

You should just be able to launch the JVM with one of these programs, and it'll let you scale the speed up/down with a slider.

Are you sure they aren't just working at the originally intended speed ? Grin. This problem is quite unusual for java games because of the wide variety of systems on which they are played. This forces authors to quickly fix the CPU speed-dependency bug...

could you perhaps give us a link too?  Smiley

for(int i = 1; i > 0; i++)
{
System.out.println(i+" cups of java downed");
