Random slowdowns on PS Games with Retropie 3 B
-
@tiagop when you say you ran updates, do you mean you are updating the psx emulator?
Also hold off on reflashing the image for now, let me test tomb raider out with the standard clock speeds tonight and I'll report back my findings.
-
@quicksilver Yes I've updated all the installed packages. Thanks! :)
-
@tiagop If you have two sd cards then you can use one to install a fresh 4.3 image on it and put Tomb raider 2 on there to see if it makes a difference.
You wont have to update it ..4.3 should work fine.
If the slowdown is gone then you know it's software related.It's also always good practise to use sdformatter when formatting your sd card before writing your image to it. (overwrite + size adjustment 'on').
-
@tiagop are you updating from source or binary?
-
@quicksilver From binary but I tried to update from source yesterday.
-
@tiagop so I just tested tomb raider II on the practise course. With my pi3 running stock speed without the enhanced resolution the game ran very well, a few frame drops here and there but I suspect that it may have been that way on the psx. With enhanced resolution turned on without the speed hack the game gets choppy and slows down. With my pi3 overclocked I have no issues at all.
If you have a spare SD card flash a new image, don't do any updates, just add your rom and bios and try the game again. Lets try to narrow this down.
-
Just for clarification, have you confirmed that it is effectively a frame rate drop by turning on the "Show FPS" option in the Video option and confirming that there is effectively a drop there?
That can help narrow down whether it is indeed a performance issue or some other kind of problem (bad ROM image, something else).
Just a thought.
-
@pjft When I use Show FPS it shows 59 FPS even during the slowdowns (I suspect it updates only every 2/3 seconds).
@quicksilver Thanks for testing it out, I'm gonna try to use a different ROM too (since TR II has like 3/4 different ROMS) and see if it's actually a bad ROM. Is it better to use a NTSC or PAL ROM? If I still have the same problem with a different ROM I will flash a new image on my spare SD card to test it!
-
@tiagop NTSC is almost always better (no black borders on the top and bottom of the screen and many games play slower in the PAL format). I remember back in the day my PAL version of Tomb Raider 2 had a pretty choppy intro..while the NTSC version is completely smooth. I'm glad those PAL/NTSC days are over for newer systems.
PS1 games in the bin cue format are the most reliable in my opinion. Eboots (.pbp = ps1 psp format) occasionally have issues.
I think my copy of Tomb Raider 2 has many bin files, which is a bit cluttery but works great.Pi 3B , 64 GB Sandisk ultra flashdrive, 19 systems, 872 hand picked classic gaming gems :-) Dual shock 4v2
-
@bobharris Mine has loads of .bin files too, I hope it's just a ROM problem that's causing this. I can only test it later or tomorrow unfortunately!
-
@bobharris @tiagop I tend to compress them to PBP files (PSX2PXP files). Saves space and I haven't had an issue with loading times despite the compression.
I'll give TR2 NTSC a go, see if I experience slowdown. I'm sure I've got it somewhere :P
-
@stoo Thank you, by the way I still haven't mention that I'm using the ROM Tomb Raider 2 (v1.3), I can't remember which version I used on the PSP
-
@tiagop That's exactly the version I'm using.
Ok, the slowdown is the game itself. Tried it on my gaming PC which can run lr-psx-beetle without any problems. Native resolution, native everything, there are HUGE framerate drops in the training section.
Game should be called Tomb Raider II - Starring Least Optimized Engine and Least Responsive Controls
-
@stoo Thanks for testing it, then surely the problem is in the ROM? Glad the problem wasn't on my RPi, I will try to test it later but just the Tomb Raider II (no version thingie) @quicksilver is this the ROM you used since you had 0 problems?
-
@tiagop It's the exact same version as I use. There is some judder when panning around in a new area, but that's it and that is normal. Can't you post a video on youtube showing the slowdown?
Preferably at the worst spot (speedboat venice?).Then we can see if it's normal or not. -
@bobharris I will try but I can only do that on the weekend :/
-
That's me playing. I had fun, it's been 20 years since I played this part, which you can see as I got lost at the end. :-)
But the point of the video is: No noticable slowdown at all when riding the speedboat. And I even enabled enhanced resolution (with speedhack), bilinear filtering (smoothing) and a scanlines filter (which combined is often too much for the Pi 3 to handle on many ps1 games without overclocking).Does the game also gives you the option to play demos of Chicken run and Timesplitters? (Then it's exactly the same version).
-
@bobharris Yes it is the same version, Is that a 1080p TV? My raspberry is rendering at 1920x1080 (defaults), could it be this? In that same zone as the video I notice minor slowdowns on my game yet on your video I don't see them. Thanks for testing it
-
@tiagop Yes 1080p tv and yes 1080p resolution. I only play N64 games on a lower resolution.
-
@bobharris I'm going to try to make a video later today or tomorrow to show you what happens
