I cannot get the memory setting to work above 1.5gb.

I am running windows7 x64 and have both java x64 and java x86 versions installed.

I have replaced the original ""processing\libraries\opengl\library" files with the amd64.jar files.

support from here: http://wiki.processing.org/w/64-bit_Support

this is the summary message I am receiving:

Could not run the sketch (Target VM failed to initialize).

Make sure that you haven't set the maximum available memory too high.

For more information, read revisions.txt and Help ? Troubleshooting.

I am not sure what I'm missing...

I presume are aware of this discussion that suggests that you must use the 64 bit java to use more than 1.5G on Windows. I currently have my 64 bit linux running quite happily with 2G (which is probably handy for sketches that use sunflow, which requires a minimum of 800mb).

Actually reading the comments from Randolf Richardson and Emir in the linked discussion suggests to me you might want to consider ditching Windows it eats memory, further Microsoft crappy licensing extortion policies even restrict memory usage....

Certainly any 32 bit Windows users are short changed in the memory department, follow the two posts links in the discussion above.............

I downloaded and ran Processing for Windows (without Java) which downloads as Processing 1.2.1 expert. This seems to be limitless in my memory setting on the x64.

Am not sure what difference there is between it and the regular, but it seems to be running the same scripts I wrote in the other version. Just FYI for anyone with the same issue.

I doubt whether it will actually be limitless (I think Microsoft impose a per process limit for supposedly technical reasons, but apparently it seems to depend more on how much you pay for the OS see the discussion link in my previous comment).

However this seems an important bit of information, which I think should get onto the wiki (the included jdk is 32 bit, which explains why you were so limited before).

It is only recently that people figured out how to get opengl to work in 64 bit operation (on Windows) so people weren't that interested in installing the 64 bit jdk. Perhaps your findings will encourage the uptake.
