Lime 8.2.0 runs worse than 8.1.3
After upgrading Lime to 8.2.0 I noticed that it was running worse than on 8.1.3
After doing a bit of testing on the OpenFL bunny mark demo it seems to run worse
This is on lime 8.1.3 with 9.4.0 and git hxcpp
After upgrading Lime to 8.2.0 and keeping OpenFL and hxcpp on the same versions I tried it again
The CPU usage is almost DOUBLED and the memory also increased as well.
More testing should probably be done as I havent tried on other targets yet.
I confirm that this is a possible problem. I ran back-to-back tests with my bunny mark and noticed large FPS variations, namely an 84-60 drop off, which is not huge given my processor's speed. These only occurred on 8.2.0, and openfl versions did not seem to affect this number; using 9.4.0 or 9.2.2 did not appear to change performance. HL performs poorly, making the problem noticeable. from drop-offs of around 80 FPS.
I have ran a bunny mark sample in openfl with both lime 8.1.3 and 8.2.0 but I'm not getting the observed symptoms. Though that may be because I have a beefy computer.
runs fine for me even though my pc is 16 year old-ish

Keep in mind I was testing with 200k bunnies It wasn't noticeable at first
Testing with the BunnyMark from lime-samples and openfl-samples didn't appear to have any difference on the Lime version used.

| OpenFL 9.4.0 + Lime 8.2.0 |
Except for the high GPU usage (which is expected from an iGPU) CPU and memory usage were roughly the same.
If it's worth mentioning I compiled to C++ target on Release, using git hxcpp 4.3.68

Very interesting since I've seen people report it running worse and people report that it is running about the same. May I ask what your pc specs are?

Is it possible it only runs bad on certain hardware? I have a ryzen cpu and a nvidia gpu.
on develop (abb92a2a849a7ae18d5112fa647e4e6e6f28919d) and OpenFL 9.4.1 seems fine on my laptop
Specs: CPU: 12th Gen Intel(R) Core(TM) i5-12450H GPU: Intel UHD Graphics
Perhaps something else changed in the initial test?
For example, are we talking about Lime 8.1 and 8.2 on Haxelib, or are these compiled from source? If compiled from source, which compiler, and which processor architecture? We could be seeing differences in Visual Studio versions, or X86 compared to X64 for example.
If the Lime main loop was changed, a bad main loop can also have this drastic of a change.
Oh, one more thought would be DPI scaling, or monitor refresh rate. I forget what changed in Lime 8.2, though if either of those features were better supported, those could have an impact.
