I don't own the same specs as the issue reporter (GitLab issue #5124). Could anyone check if these changes mitigate the issue.

This PR addresses the excessive CPU usage observed when controlling ENE-based DRAM RGB modules on Windows. Users reported CPU spikes up to 10% when enabling multiple RAM modules, caused by repeated calls to pawnio_execute during SMBus transfers.

Hi, I tested your branch.
I had to rename the variable LAST_COLOURS to lowercase (last_colours) in order to make it compile.

However, even after compiling successfully, I’m still seeing high CPU usage (around 21%) whenever I use effects on the GPU or on the memory modules.

Thanks for your work on this!
