Just a simple frame difference (could be any op, but I'm used to using
When i try an implement this in open gl using one of the math shaders and a feedback into a blank gl.slab and into the tex2 input (since i cant use [t l l]) it doesn't end up working the same way, or if i do get it work it ends up strobing twice as fast. I supposed having a jit.change at the beginning of the effects chain could work, but that messes up other elements (ie stopping the video but still changing effects parameters move normally)
Could the answer be to just slow my metro down to get less of a fast strobe?
Any advice on other glitchy/strobe effects would be great..I'm trying to get rid of all of the non-open-gl effects in my performance patch, but haven't hit glitch gold yet
