The ram and cpu meet the minimum, but your GPU may be causing the issues, for it seems to be very old. Given the fact that the scene you posted uses renpy's model based rendering to color-correct and apply effects to the sprites, I think it may not be playing well with your gpu. I will definitely be adding an option to disable the color correction and sprite effects since it is gpu-dependent.
In the meantime, have you tried integrated graphics, pressing shift+g using the ANGLE2 renderer, or the 32-bit version of the game?
I apologize that ikimashou is a pretty resource heavy vn, and that I overlooked the folks with lower-end PCs. I'll be working on troubleshooting this, thanks for the report
