MiSTer FPGA Forum

I always thought VRR/Freesync on MiSTer was just a hack to help panels support odd frequencies ? The frames are sent with the variable rate flag to fool the scaler, it's actually more handy on TVs than monitors which have more flexible scalers anyway That makes sense. Proper G-Sync also needs a FPGA in the panel scaler to function properly and is ...

Biggest thing I've discovered with this device so far is that you really should use vrr_mode Looks like a nice device to test with. VRR/Gsync/Freesync will come out on top due to its built in use of Quick Frame Transport(QFT), which causes the wait period(buffer) to occur after the frame is displayed, rather than before the frame. Which happens on...

Is this from a Zero2 just running on stock? Or is this while also attempting some of the mitigations you mentioned like reducing the Polyphony to 200 or overclocking it to 1.2GHz? Was Pi Zero2 at 1.2Ghz, Polyphony=256. Have tested at 200 and 140 polyphony at 1.2Ghz. Was still not good with Arachno, most sound fonts worked just fine. Its just one o...

Hmm, good to hear that most would work, though still wished it could be on par with a Pi4. I had no idea it was using that much of the PI4's power that the Zero 2 would still not be enough to match it. Pi4 stock is clocked higher, 1.5Ghz vs the 1Ghz of the Zero2. I don't have a Pi4 setup for MT32-Pi but I suspect its possible that in certain scena...

I was wondering about the Viewsonic XG2431. How good is it really to use with a MiSTer and how bad is the flickering? The problem is I have no reference and I live in Europe (where the monitor isn't sold), so I'm thinking about importing one myself, but that's costly so any information on the performence you can give me is much appreciated. Does t...

I was hoping that the PiZero2 would be powerful enough to fully replace a Pi4 as a MT32-Pi, but it's sad to hear that with games that have more complex soundtracks you would need an overclock to pull that off. Got around to testing with Pi Zero 2 W. There is a couple of soundfonts I had issues with, namely "Arachno" but most soundfonts w...

I believe the pixel clock limit is somewhere around 180Mhz, I can't remember. Could the vblank be increased at 1080p@60hz? Increase to Quick Frame Transport(QFT). https://forums.blurbusters.com/viewtopic.php?t=4064 I guess that leaves ~+30Mhz to work with? A larger vblank could reduce latency by forcing the scan-out to start sooner while also impr...
