Change wheat.

[Lothaudus]

At least as a temporary measure, draw up the current stuff as a series of half a dozen sprites that fit on half the tile and then make it two sprites for the wheat please.

Wheat does seem to lag a lot more than the other crops. It does also seem to be the fastest growing field?

Having some sort of "alternate wheat" option would be interesting. Even just to see what affect it has on the lag. If it has none, then obviously something else other than drawing the sprites is the cause.

Do this at LEAST until you can figure out wtf is causing this game to lag so badly and consume so many resources to begin with.

Well... It is built in Java...

I know someone on a quad-core processor with the same RAM as me who gets worse lag than I do, even though I'm only on a dual-core. Go figure.

It's really not to do with Java from what I hear people who speak of code, rather poor implementation of OpenGL as Loftar himself candidly admits.

Indeed. There are lots and lots of real reasons to dislike Java, but performance isn't really one of them; not anymore, at least. I already wrote about it in some other thread, but Hotspot is quite a cool JIT implementation that does a lot of really impressive optimizations that normal static compilers could only dream of. Sure, it's easy to write Java programs so that they are slow, but that belongs with those many other complaints about Java, and I've managed to stay rather clear of them, to my knowledge.

While profiling*, I more often find that while it's true that some time is spent doing CPU-bound calculations (and those are probably possible to optimize further), the vast majority of the time is actually spent in the OpenGL calls, which indicates to me that I'm doing something wrong in my usage of OpenGL.

* If you want to try yourself, run the client with the "haven.profile" system property set to "on", and press the ` or ~ keys to bring up profiling on the mapview or the whole draw cycle.

Cant you use direct3d instead?

[lordrio]

Then this game will be a windows-only game.

Go to hell. Seriously. DirectX/>OpenGL. It's how one uses it.
