Hey All,

I recently updated monkeylogic and started running a userloop script I wrote about a year ago, which worked fine then. Now, I am getting the error for skipped frames on every repetition. Anyway to troubleshoot this? Let me know when you get a chance. Thanks a lot.

You did not provide enough information. There hasn't been any change that may affect screen updates. Does the latency test look okay? Did you run in the simulation mode?

Latency test attached, and simulation mode produces the same effect. What additional details can I provide?

For example, is it only NIMH ML that you have changed? Is there any change in the hardware?

Your latency test does not look good, so it is not the script that is a problem. Try changing the main display as suggested in the manual.

No hardware has changed to my knowledge (I'm not the only one using this machine, so I will double check that), and the monitor is set to being the main display already, with the 'extend display' setting.

Maybe the monitor configuration has changed due to driver update or new hardware. This is a matter between Windows and your monitors, so you just have to try different configurations, for example, by plugging the monitors to different ports, making a different monitor the main display or rearranging their relative positions.

So to solve this, ultimately, I had to change the refresh rate on my monitor from 100 Hz to 60 Hz. The subject screen is a CRT which gets info from a spliter, and I'm guessing something with the windows October 2020 updates related to refresh rates has messed w/ how things were previously working. Since I'm not using stimuli @ above 60 Hz, I don't believe it will be an issue (also I'm not studying any obviously visual region in the brain, so what tiny differences may be caused by this will likely not effect the end result). Thanks for the help Jaewon.
