We’ve seen in recent months that graphic intensive plugins cause glitches in Reaper on Windows. The audio thread is not affected, but the VU meters and scrubber often stutter a little. To combat this I’ve added a new
openGL() identifier for the form widget. It will cause plugin graphics to be rendered using the GPU instead of the CPU software renderer. It is off by default. In plugins that are constantly updating GUIs it can lead to better UI performance and in some cases better CPU.
I can’t say whether performance will always be better, it really depends on what you are doing. But it is worth testing before you share your plugins. It’s available to test in v2.7.7 which is currently being built in Azure.
