Game lags and unresponsive after playing half the game

[MrBear]

Hi there everyone!

I'm having this issue with my project, after you have played through to the middle of the game it starts lagging and is unresponsive. You see I have checked through my script.rpy multiple times looking for a error around the point that it starts to lag and become unresponsive. I also tried running the Lint and it returned no results and I have also tried recompiling. Almost forgot to mention it does not pop a error at all when the problem begins. I'm a bit more than a novice with programming.

Here is the point in the game that the problems start. Edited out the actual dialogue but please if you see i'm handing something wrong don't hesitate to let me know!

My question is: How have you guys handled similar problems?

While running your game, shortly before where it normally lags out, press Shift + D and then press F4
This should bring up a small screen telling you how much memory you are using.

Intresting! so as i approach the area i notice my textures are way high(74) and my cashe is like 58% right before it lags out.

Does this happen gradually, or suddenly?
I suspect Ren'Py might not be performing garbage collection for some reason.

it slows down about 2 images, stop and unresponsive, comes back up on another image thats located 2 images ahead of the stop then continuly freezes randomly after that point.

Try to rename all your 'frame___' to 'bg frame___'-like.
This should make Ren'Py replace all those images onscreen, so only one of them will be shown at a time.

I'll try this fix tonight, thank you and I'll post a update later on
Edit: unfortunately this fix didn't work. I wonder if maybe there's a issue with my project and I should just start from scratch? Before I do that I'm going to try to work with the garbage collection.

Alright so I did end up starting my project over. The problem begins at frame47 so I'm guessing it has something to do with the image file itself. Next step is removing it completely to verify it is causing the problem. Time to research how/why a image would do that. Any ideas?

When you do "show frame123" it does not replace previous frame, but just show frame123 on top of frame122, frame 121 etc. This likely reason why you game is lagging.
As Alex pointed out either rename your images so renpy treat them as having same image tag or use "scene frame123" instead of "show frame123".
If you already tried that and lag still persist then likely something else to blame. Just to be sure, check your images so they all same size or at least not bigger than screen. Normally if renpy able to load image it is good enough to continue, there shouldn't be any lags due to loaded image content.

Thanks for your response! I was thinking about doing this. I will try this fix, and Thanks to everyone whose helped me with this problem!

Edit: Even this doesnt work
