@rmbell34 I also use the 8BitDo SN30 Pro+. The problem with the Switch mode is, rumble/vibration/haptic feedback doesn’t work (for games that support this feature). This only works in Windows (X-Input) mode. For this mode to function properly, you need to install/update the xpadneo driver. This should fix the long loading times and can be done through the RetroPie-Setup script. However, in Windows mode the star and home buttons are not supported.

@buzz
You have a good point.

I had a very similar problem to this thread. I replaced my Pi 3 retropie with a Pi 4 and retropie was behaving in a jittery fashion with Emulation Station and the games weren't smooth. I also have a 4K Samsung Smart TV as did the original poster. Although I wasn't using Amiberry, I was using mame, daphne, and jzintv and I figured the same solution that @gordonfreemanjr used would work for me. So I added the five lines to my /boot/config.txt file that he listed in his "IT WORKS" post but lo-and-behold it did not work for me. tvservice -s was still showing a 4K connection when I expected 1080p.

My solution was simple with a twist. Starting from the stock config.txt, I uncommented and modified the following:

hdmi_group:0=1 hdmi_mode:0=16

It was necessary for me to add the :0 to get it to work. Now there are no jitters, the motion is smooth, and tvservice -s reports a 1080p connection.

I find even with a pi4 i can't run anything past 1080p, also make sure you have your game mode set on your tv.

I will admit i have not attempted to use advmame yet, so i am just kinda throwing out suggestions.

@tripplies Yeah, those rules that we old guys don't know anymore. ;)

Welcome to the club of 5+ posters.

The under-voltage notification is a flash sign appearing at the top of the screen.

Did you use the Raspbian Lite or the desktop image to install ? Is there any reason you're not using the RetroPie provided image on the site ?

Yes lr-flycast is slower than reicast, and lr-redream doesn't start at all

@ballplaer14 said in All Roms and Emulators Running Slow:

@mitu it works! Wooohoo! You’re the best. Thank you so much.

Actually that GPU can handle that. I think the issue is the frequency. My desktop defaults to 30hz initially on my 4k TV which makes everything look like its running like garbage when internally it is not.
You might get a clearer picture by putting it back into 3840x2160 then setting the refresh rate to 60hz where it should be normal. Should be...

Alright i know the issue is the refresh rate:
[INFO] [Video]: Average monitor Hz: 30.000300 Hz. (0.834 % frame time deviation, based on 2048 last samples).

@Sano
Wow!...
Yes, this is most likely it. Found this discussion on the same topic.

@megaJekan I don't use bi-linear and my monitor is a PC CRT (VGA converter). I would say it looks ok, not spectacular or good. Especially Arcade games are problematic, but that is another story. On the PCSX-ReARMed I use the Shader "scanline.glsl" (Filter:Linear, Scale:Don't care) from emulators SHADERS menu. Honeytly, this does not look that great, but it is the only one working so far. On some other consoles I even use the "sharp-bilinear-scanlines.glsl". On the PSX some games look great with that sharp one, but some others are ugly. Crash Team racing is unplayable ugly with the sharp one, thats why i use standard scanline shader. I suppose it have something to do with different resolutions used by the games.

If I am reading correctly all you need is to get emulators designed for x86 processors, mednafen for ps1 maybe? Install it same as you would mame. RetroPie’s default emulators aren’t designed for pc

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.

@pjft Hi thanks, yeah DD was one of them and a couple of other Arcade. No worries, maybe its a common thing with particular titles then - Thanks
