@dankcushions Ok, now i see, thanks

@luckyluca said in Pi400 slow stuttery dremcast redream emulationI:

Regarding overclocking, do you know what the default gpu clock is for the pi400/pi4?

I think the default gpu_freq is set to 500 (Pi4), I assume is the same for Pi 400.

@Rion I would've liked video evidence, but o well. I don't see it.

@Kentinator there are several threads concerning N64 Emulation with the Pi, but to say it with a few words: your experience nails it.
Mario64, MarioKart64 and a few others work well, a lot of other games do not.

Just to give this thread and all you guys some closure, I have not experienced any slowdown on PS1 games since installing Retropie 4.4 from scratch. Perhaps it's the new version, perhaps it was some tinkering I had done and that has now been erased. I did notice that PS1 games tend to slow down on my Pi2 when enabling enhanced resolution, either with or without the speed hack. I have not yet tampered with the overclock settings and I'm not sure if I should, since it's a Pi2... Otherwise I'll simply stick with the bilinear filtering option, which slightly improves graphics, and wait for the Pi4.

I do have heat sinks and a fan, I will try another power supply tomorrow and I will post my overclocks.

I tried it with overclock and stock and it behaves EXACTLY the same.

@dankcushions said in Slow downs:

are you sure this isn't native slowdown on the original hardware? super castlevania IV is particularly infamous for this, in the bits you mention. eg https://forum.digitpress.com/forum/showthread.php?131637-Super-Castlevania-IV-Slowdown

Good idea! I think your on to something - RetroPie emulating things TOO well - including slow down that's there on the actual console itself.

I experienced this first hand on a Pi 3 when I first started messing with them - but with Castlevania (1) on NES. Think it was the first boss which had bad slowdown. When I tried it on my NES console itself (on a glorious retro CRT TV ;) the SAME exact thing happened. Thus the emulation is emulating how the actual SNES (or NES) played that particular game - slowdown and all.

@bmos are you using the RetroAchievements feature? It can cause this issue. The retroachievements.org server isn't that powerful and this delay can be caused when RetroArch is trying to communicate with it.

@ND Thanks for using my Vine to demonstrate. I was using the Pi2 at the time I filmed the Tobal2 Vine (English patched version btw). And I recall that this was using unfiltered textures. But it ran fantastic given the fact that the game itself ran in Hi-Res and 60hz.

I just upgraded to a Pi3 courtesy of the missus and so was quite surprised to see your video running the game slow on Pi3. But glad to see it's been sorted so I'm keen to play this again soon. 😀

Thank you. :-)
