Issues with Dreamcast emulators

Hi all,

I'm noticing a lot of slowdown with Dreamcast games specifically when using either Redream or Flycast on a Windows 10 PC with a 3070. Power is not the issue here.

I've tried several roms, and several setting configurations, but everything seems to be running too slow or stuttering. Examples are Ikaruga (too slow of FPS) and Crazy Taxi (stuttery; arcade version is fine; also, lots of pop-in).

Any general advice is most appreciated!

You could try the following:

1. Verify that your display runs at 60 hz. (or 120 hz.) during gameplay.

2. In the nvidia control panel > Manage 3D Settings > Program Settings > Add, add retroarch.exe and redream.exe and set the Power Management Mode to "Adaptive" or "Prefer Maximum Performance".

3. Use NTSC games. (Or PAL games that have a 60 hz. setting.)

4. Verify that Redream and RetroArch are using V-Sync.
