These donut things are great but are so slow on my computer. Anyone else have this problem?
u/cantelope

lewdev, there's known performance glitches with canvas in Firefox on Linux. Guessing that's your stack. Try Chromium?
u/tomxor

I actually always found Firefox canvas way faster than chrome, on Linux at least. Including this one, 30 FPS in chrome, but 60 FPS in Firefox, I got a new laptop this year so probably even slower in chrome on older computers.
u/tomxor

@cantelope You might be thinking of the subpixel aliasing issue on Firefox that appeared when they flipped hardware rendering on by default. That affected a lot of dweet rendering, I reported it a while back and it's been fixed in release since v128
u/cantelope

whatever causes the firefox+canvas+linux thing, somehow i always correctly guess the stack... whatever that means
u/lewdev

I was on win11 on my laptop, but it was slow on both Chrome & Firefox. It's smooth on my desktop Win11, which is much more powerful.

u/jpthinker

So cool!
u/jpthinker

Reading through the code, this is so clever! I like how you combined the black background fillrect with the i variable's initialization, and how you used clearRect to get away without doing any fillStyles.

The target

Neat, it looks like craters within craters. The target was hit on the same spot by bombs of smaller and smaller blast radiuses.
