custom opengl compressed texture

I am developing mobile games on windows. Our image resources are in the PVR-TC 4 format. When we run our game on simulator, images are decoded by CPU which is really slow, as our PC graphic card don't support GPU decode. Is it possible to make PC OpenGL support PVR-TC or ETC hardware decode?

You cannot force an implementation to implement a particular extension or image format.

Your best bet is to convert the images yourself offline. That is, instead of loading images of a format your hardware can't handle, load images of the format that it can.

After all, it's not like the images are originally in PVRTC format, right? They were originally authored in a regular format like PNG or whatever, then converted to PVRTC. So just add another conversion for S3TC or whatever format desktop hardware actually supports.
