SubRetro Posted December 21, 2018 Share Posted December 21, 2018 Hello LB Community!! So I have a question and I am sure a lot of it is going to require some more testing on my part and that is fine. Current Test PC Build before migrating to new built PC - Intel Xeon 8 Core PC -24GB memory -1060 8GB GTX -WIN 10 -ViewSonic 1ms 27 LCD Monitor connected via DVI (Highest Refresh rate support is 80hz I imported my MAME 193 full merged set into LB 9.0 (Now running 9.1) and have been playing several different games with no issues. I run the MAMEUI version of the emulator. What I did notice when playing a few rom sets of turtles arcade I noticed some screen tearing on the top mid section at different times during gameplay. I have ran the rom set on previous versions and don't recall ever seeing this before ( I have played a lot of turtles arcade). I am wondering if there is some known issues related to certain ROMs running certain versions of the MAME set or maybe something I can tweak? There are some other things I know I can try right now to see if it makes a difference such running a different MAME Turtles ROM set or another MAME emulator ( I use retroarch for most older systems).

The thing with MAME is that you dont really want vsync on at all. A lot of arcade games run at some weird framerates, you will often see framerates like 55, 58, even 61, 62 etc. The point is there was no standard and as they were on CRT's it didnt really matter what the exact framerate was as they still worked fine on a CRT. The issue now is we are all using flatscreens which have specific framerates like 24, 30, 60 etc and anything that deviates from those will tear. The problem is though if you turn vsync on those games will lock to a 60 refresh and if say a game originally ran at 55 it will be sped up to 60 to match the refresh of the screen, so some games will run faster than they should which obviously isnt correct. I personally leave vsync off and let the games tear if they need to in order to keep the original game speed correct. Hope that helps somewhat.

SubRetro Posted December 21, 2018 Author Share Posted December 21, 2018 Yeah I don't recall if I I have vysnc on or not but I will have review. Also I am not just playing old arcade games but current PC fighting games. Wondering too if plugging in HDMI into TV screen instead of a monitor will make a different.
