Hi. I have a setup to play GroovyMame on a CRT. TAP is working perfectly fine at 320x240p but groovymame execute TGM at 640x480i (The i, is probably because my monitor is 15khz and cannot support 480p). I readed that TGM should play @ 240p exactly like TAP but for some reason, its not. I checked in another pc with an LCD and shmumpmametgm and it seems that i have the same problem, TAP at 240p and perfect and TGM 480 (this time 480p). Could it be because of the roms? TGM also feels a bit laggy, even in shmupmametgm in an i74770k... TAP is perfect. Any ideas?
