I would like to use PsycoPy to present images with a precise timing and I have run into an issue. I get a very low framerate of 10-20 fps. I made a trial in “Builder” with blank screen for 60 frames and a stimulus of one image (1920x1200 pixel 24bit bmp) displayed for 60frames. I have edited the py-file created by the builder, to include a TextStim that displays frame count and frame rate (window.fps()).
The image is displayed for 3-4 seconds (even though the monitor runs at 60Hz) and the TextStim indicates that the fps is 10-15. window.fps returns 13fps initially but changes to 0fps after the first flip.
I have set the pythonw.exe to high priority and it uses a full core on the cpu. Do I need to buy a dedicated graphics card to achieve over 13 fps?
build in graphics intel HD 530
monitor 1920x1200 @ 60Hz
Thank you for the help!
