Viewing post in OLD TV Filter for GameMaker comments
Hello, i know this post is from 1/3 years ago, but i found a way.
Into "scr_OLDTVFilter_Draw" in line 16 i think, have the command "gpu_set_tex_filter(true)", set it to false or just remove it.
Also, if you have a problem with HUD, the only way i think to fix that is making a surface and put everything of the HUD in it and then modify the script at the beginning to merge the HUD and Application surface together to be draw by the draw script.
