it doesn't work, i assume it's because of the Ren'Py 7.4 (Older versions of Ren'Py supported a software renderer, but this has been removed).

A small fraction of systems may experience problems when running hardware accelerated Ren'Py games. These problems are often due to buggy graphics drivers, and so your first step to fixing them should be to check for an update to your graphics card drivers.
If upgrading your video drivers does not fix the problem, you should consider switching video renderers, using the following steps.
- Hold down Shift while starting Ren'Py, or press Shift+G once Ren'Py has started.
- From the "Graphics Acceleration" menu that appears, choose the renderer to use.
- Choose "Quit", then restart Ren'Py.
We suggest trying the GL and ANGLE renderers. The GLES renderers may not function on desktop hardware.
On Suspend/Resume
We have had reports of systems that lose textures when a computer is suspened and resumed. This is likely a problem with the computer or its device drivers, but it is possible to force Ren'Py to reload the textures by resizing the window, or pressing the F key to toggle fullscreen mode.

that's all I found for now ...
I hope you can find a solution.
