Smooth scrooling in 50Hz ?

Hello, i was wondering if there was an immediate way to have smooth animations in PAL games with WinUAE by a PC monitor set in Hz. By immediate i mean without installing an application that forces actual GFX card to use 50 Hz.

Can the refresh rate be adjusted independently of the sound speed in WinUAE, like in Mame for example ?

I remember i tried a setting in WinUAE that allowed to keep the PAL sound speed by setting the Amiga as a NTSC one, but i can't manage to retrieve what i did...

I would want to keep games in PAL but have smooth animation. Is it possible ?

Thanks in advance for your help.

How could you possibly have smooth 50Hz animation if your graphics card is not running at 50Hz (or 100Hz)?

I was under the impression that if your monitor advertises to Windows it is 50Hz capable then full screen refresh rate change works in WinUAE today?

My monitor reports three refresh rates (24, 50 and 60Hz). I run PAL, the monitor is set to 50Hz, the scrolling is smooth.

Probably connected via HDMI? 50Hz is in the HDMI standard. VGA/DVI connected monitors mostly supports only 60Hz unless you force it to 50Hz via external tools or registry hacks.

The only utility that worked for me on my LCD monitor connected through DVI was CRU. The monitor only supported 60hz but also worked in 50hz beautifully.

I could create a 50hz native resolution which I used with WinUAE. Now I use a CRT monitor for WinUAE.

My LED TV is HDMI, but my Radeon is DVI only, so I use a DVI-HDMI adapter, and I get 50 Hz smooth scrolling by selecting "50 Hz PAL" refresh rate and V-Sync in display options in WinUAE.

I think it depends on TV/monitor model and graphics driver. My LG-TV and Radeon HD4000 graphics card is good thought.

I needed to enable hdmi out (or maybe TV out, not at my pc right now) to give my 50hz output options. Amd 5870, very recent drivers

I used "PC strip" by the past to force strange resolutions not listed under window by the graphic card driver.

Does anyone know about the settings I used to have a game running in 60Hz with the sound running at 50Hz ? I can't manage to find it again :/.

Just use 'cru'. Get it here (CRU DL) and follow the guide in the forum, to create a monitor.inf file that enables 50Hz on your monitor.
Now set your desktop to 50Hz and run UAE in Fullwindow mode.
Enable low latency v-sync and set the refreshrate to 50Hz in the diplay panel.
Run a demo or game in PAL with lots of scrolling.

I use these settings on my AMD Radeon HD5770 via DVI for perfect smooth 50hz in fullscreen.
Win7 sp1 x64 + Catalyst 14.9 drivers.

Thats a pixel perfect setting retroplay.
The above setting only work for me if I use a native 50Hz monitor or force it with cru.
With the original driver I will get a black screen using 50Hz settings in uae.

But having 'real' 50Hz lets you enable low latency v-sync instead of that 50/60Hz VS stuff.

This is how it works on my system.

1) open CCC
select "My digital flat panels" in left menu
add 1080p50 standard as shown on right
like this:



2) in winuae under Host/Display these are my settings



3) these are my Host/Filter settings, I had to play around with these a lot to get decent looking scanlines without that ugly doubling up of scanlines that can happen with winuae (You get even scanlines all down the screen, except 1 where its doubled up!)



Hope that helps a little, works beautifully for me.

edit: Im using a dell 1920x1200 monitor model:2407wfp connected by dvi only - no hdmi cable/connector/converter is attached anywhere.

Thanks for all guys, unfortunatly i can only try the CRU stuffs here. Also i'm looking for a solution that doesn't need to select manually a 50Hz refresh rate from the windows desktop, and allows to go back to the initial desktop refresh rate once WinUAE closes itself.

My refresh is set at 60Hz in Catalyst, WinUAE automatically switch to 50Hz when executed and once I close WinUAE it goes back to 60.

CRU created mode should appear in WinUAE's resolution list, select it, select correct refresh rate (if there are multiple available), select fullscreen with vsync.

Refresh rate can't be forced by application, it needs to be supported by driver and driver needs to support EDID software overrides. (Everything should support it, except nvidia in surround mode, it broke in summer/fall 2013 drivers and probably still is broken..)

Exceptions (that don't need any manual config) are g-sync and freesync monitors (with matching supported gpu) which should be perfect for emulator vsync support, emulator is not anymore forced to sync with display but display syncs to emulator which practically removes missed frames completely and tight timing requirements without losing low latency.
