Monitor refresh slow

[Richardgregory]

Hi all.

I'm noticing that on some titles such as a fast scrolling title like Xevious the refresh draw rate is rather slow making it a bad gameplay. I'm using a quad core pc with a decent video card. Am I missing a setting in te MAME setup to best optimize the video play?

Is it running at 100% ? (press F11 during gameplay IIRC to display)
If so, that's probably just how the game is.

If not, do you have HLSL enabled?
If HLSL is enabled, try reducing the prescale.

i would say xevious scrolling is classed as slow by the way, not fast

Thanks. I do have HLSL enabled. Can the Prescale setting be set in the Slider Controls after I press the tab key?  I don't see the Prescale option unless its some other name?

No, has to be set in mame.ini just below where you enable HLSL.
If reducing it works, you can add the line to the xevious.ini (whatever the rom is named) in the INI folder so it doesn't affect other games.
If there isn't an xevious ini already, just copy mame.ini over to the INI folder and rename it to match the xevious rom.

I had to reduce the prescale on the games that had discrete audio because they are more demanding than other old games.

Thanks!  That fixed it....reduced the prescan setting and bingo.
