OS: Win10 with a NVIDIA Geforce RTX 3080 Ti GPU and monitor at 240Hz refreshing rate
PsychoPy version: 2023.1.0
Standard Standalone? (y/n): no, installed library via pip
What are you trying to achieve?:
We are trying to present a high-frequency visual stimulus blinking at 180Hz using the visual api and radial stim from psychopy.
What did you try to make it work?:
We used a monotonic clock from the core api to act as a timer from which we count the times in which the screen should be updated yielding the blinking stimulus.
What specifically went wrong when you tried that?:
Presentation works great at low frequencies (for instance, 10Hz). At higher frequencies, anything above 120Hz, we get dropped frames, stimuli that doesn’t blink and longer times in between clock readings.
Any suggestions of how to use psychopy for high-frequency visual stimulation?
