Class316 Posted February 15, 2023 Share Posted February 15, 2023 So I was looking at BigPEmu on youtube and thought "oh wow a perfect Jag emu". I have Phoenix which runs very well on my PC. But when I try BigPEmu it's slow and the sound is jerky. I tried playing with the settings but to no avail. Does this emu simply have high system reqs? Intel Core I5 and 8gb ram. I would think that's plenty for a Jaguar? Quote Link to comment https://forums.atariage.com/topic/348168-bigpemu-why-does-it-not-run-well/ Share on other sites More sharing options...
42bs Posted February 15, 2023 Share Posted February 15, 2023 BPE is the best emulator so far. It runs well on my M1 Mac (that is, the x86 Windows exe is emulated for ARM64 under MacOS).

+LS650 Posted February 15, 2023 Share Posted February 15, 2023 I’ve run BigPemu on two different Win 10 laptops, including a crusty old first generation i3. I also have it installed on a Ryzen laptop with Win 11. It runs quite well on all three, with none of the issues you describe. Something on your machine conflicts with BigPEmu. I would try running Windows in Safe Mode and have as few other processes as possible going. Is BigPEmu still stuttering then?

oky2000 Posted February 15, 2023 Share Posted February 15, 2023 I have an AMD A10 on Win 10, from memory it didn't even break a sweat running BigPemu, something like 80% CPU time idle. Core i5==AMD A10 so no idea what the problem is for OP. BigPemu is one of the best emulators I have used, it is on a par with VICE x64 easily for simple no nonsense 'it just works' and not complicated to use, apart from a lack of emulator based video capture built in (easily fixed with screen capture software is it so efficient in CPU usage) it's as perfect as emulators come by far. CD emulation is also a piece of cake. It really was one of the best emulators I have tried, a lot less messing about than with most emulators. 1 Quote Link to comment https://forums.atariage.com/topic/348168-bigpemu-why-does-it-not-run-well/#findComment-5209673 Share on other sites More sharing options...
Shaggy the Atarian Posted February 15, 2023 Share Posted February 15, 2023 Ryzen 7/Win 11 laptop here. Runs fine for me so far - only had one tiny issue while recording some AvP yesterday with OBS but it was a very short audio stutter almost 8 min in. Otherwise I've played several other games and not seen issues with 1.0.5. Really impressed with the CD emulation too Quote Link to comment https://forums.atariage.com/topic/348168-bigpemu-why-does-it-not-run-well/#findComment-5209693 Share on other sites More sharing options...

Yes BigPemu is super easy.

Class316 Posted February 15, 2023 Author Share Posted February 15, 2023 (edited) I tried safe mode the emu wouldn't even start. But it's irrelevant because the main culprit is jerky sound and I don't get sound on safe mode. I tried deleting the config files and using a fresh unzip for BigPemu, but still the same. I sound is absolutely horrid and jerky. The startup sound of the emulator as soon as you start it is fine. I don't get this from other emulators, and I've tried pretty much everything older than PS3. Including Jag emulation on Phoenix which runs flawlessly. And I just tried 4DO for the first time (a 3DO emu) and it ran fine. I've even played CD-i on MAME. As for CD emulation, the only thing I tried was Blue Lightning and the graphics were all buggy. I couldn't see the background. But I am guessing this is becuase CD emulation is not 100%?

It is the least problematic emulator in the world, there is no config at all except for things like assigning keys to joystick functions/changing the gamma of the palette to look like a real C64 on a real CRT TV etc but nothing that stops you playing games within seconds really.

I see so you are using a pre-built one that somebody probably put reasonable defaults into. I build it from source and by default it usually has an aspect ratio that's way off, the menus don't work right it takes some crazy command-line parameters and other issues. I beat it into submission eventually, but it's more work than most other emulators. 1 Quote Link to comment https://forums.atariage.com/topic/348168-bigpemu-why-does-it-not-run-well/#findComment-5209785 Share on other sites More sharing options...

Can't remember which ones as it's been 15+ years since I played the game (as you could probably tell!). Otherwise, game looks the same as I remember it on real hardware.

With certain filter effects, it barely moves. By default, it runs full screen. Sorry if I missed it... did you try running it in a window instead of full screen? That helps me a little.

crash Posted February 15, 2023 Share Posted February 15, 2023 Any exclamation points in your device manager? What are your sound and GPU devices? I've seen this problem with a missing driver related to audio hardware acceleration. Others have had it when their GPU was not rendering properly due to an opengl issue causing software rendering. Try testing your gpu with Furmark. Also probably for a Windows update check to consider other drivers that could be out of date. 1 Quote Link to comment https://forums.atariage.com/topic/348168-bigpemu-why-does-it-not-run-well/#findComment-5209823 Share on other sites More sharing options...

I did windows update yesterday before trying out the emulator, and I just updated my nvidia graphics card drivers to see if that does anything but no. Same thing.

crash Posted February 15, 2023 Share Posted February 15, 2023 I would be interested to know what that exclaimed Base System Device is. It could indicated missing chipset drivers. I don't know if you might consider seeing if there are chipset drivers for your motherboard to install, since Windows isn't identifying the thing. Maybe if you have optional devices plugged into your system, unplug them and see if that goes away, otherwise it is something inside that probably will help your computer if it gets the right driver. My VCS was performing horribly with BigPEmu because "Multimedia Controller" in the device manager was missing a driver. I had to install an AMD chipset driver package to discover it was actually an audio hardware acceleration device, since neither the Windows installation nor Windows update could identify what it was supposed to be. 1 Quote Link to comment https://forums.atariage.com/topic/348168-bigpemu-why-does-it-not-run-well/#findComment-5209863 Share on other sites More sharing options...
