DIV Games Studio always uses about 50% CPU usage on my computer


Hello, I tried two versions of DIV Games Studio(Windows). their CPU usages were also about 50%, even I did nothing(they were at idle). I think that this is unreasonable.

I have other game making programs and language softwares installed on this computer. If these softwares are at idle, their CPU usages are nearly zero.

May there be a bug in DIV Games Studio?

There is an issue due to the way DIV renders the IDE in that it is basically redrawing and rendering everything per frame. It worked well in the DOS days but nowadays things are a little different

It could be changed, but a big rewrite is needed to release the excess CPU.

It happens on all platforms, but it scales well so its basically the same performance on any hardware.

Also it is all software rendering!

Hello ahmok,

The issue is because the IDE runs in aggressive immediate mode instead of classic retained mode, and also as Mike says, for software rendering.
