Title: Tearing in Fightcade 2 - CPS3 on a CRT
Post by: Gunstar on January 16, 2023, 04:46:06 pm

Hello,

I'm trying to match my CRT Emu refresh rate to match the CPS3 emulator in Fightcade 2 (FBNeo), I managed to add the correct resolution by editing user_modes but it appears the refresh rate I've used, 59.633333, which I think is the CPS3 refresh rate, isn't correct as it's causing screen tearing. I assume that correctly matching the refresh rate in 'user_modes' will fix this?

VMMaker is showing '59.63' correctly after I set the table method to static

I think my assumption that fightcade/FBNeo is using 59.633333 is what's wrong here, anybody know what FBNeo is using for CPS3? Thanks

An FBNeo dev confirmed to me that the CPS3 speed they use is 59.59949Hz, this doesn't work with Fightcade 2's emulator, I also tried it with an official FBNeo build (fightcade 2 apparently illegally uses a branched version) and it appeared to have worked, I then intentionally picked an off-spec refresh of 60.000000Hz expecting tearing and it was also fine (thus showing there might be some sort of V-Sync going on). Despite all the V-Sync, and Triple buffering etc being set to off there appears to be something going on with the official build
