Title: FCEUltra 321x240 horz screen tearing
Post by: Chunce DeLeone on May 06, 2010, 10:03:01 am
I am running FCEUltra on an WG k7000 arcade montor/jpac at 321x240 with an ATI x550, winxp, 2gig ram, and getting horrible horizontal screen tearing.  I was looking for a triplebuffer-like setting but couldn't find one.  Does anyone know a setting to fix this or a better resolution to try?

Well, I use Nestopia at 256x240@60.11hz with these settings:

Timing Options:

Auto Frame Rate

Maximum Frame Skip 1

V-sync ON

Use high precision timer ON

Triple Buffering OFF

With these settings I get extremely smooth screen scrolling in the NES's native res. It's 99.9% the same as a real NES.  There is not any appreciable input delay either.  

For some reason that frame skip one was the magic setting.  It doesn't actually skip frames, but if you set it to zero or synchronize to refresh then it gets choppy again.

Usually the V-SYNC is what prevents tearing (but only if the computer is drawing the screen fast enough)

Identical to the settings I use and it looks fantastic.
