I use a LOR CTB32 controller with the OpenDMX driver on Vixen 3.

On one of my sequences that has periods where the lights are strobing at 50ms on/ 50 ms off, the preview window and lights weren't updating properly. It's like things got behind.

I had to make two changes to fix:

In the Vixen Options, I changed the "Update Interval" to something low, like 5ms. This fixed the preview window, but not the lights.

In the OpenDMX driver, I tweaked the thread that sends the DMX packets to send them as fast as possible. Basically changed a sleep(25) to sleep(5). This fixed the lights.

Does anyone else have this issue? If so, I can consider submitting these changes to the code repository.
