Out of Memory - Title, Menu, & Character Selection Screens

[Bruce]

Hello everyone,

I've posted my question regarding to this issue in another topic, but I think it is better for me to create a topic and post all my code.
I started learning how to add backgrounds and animations with arraylist to the title, menu, and character selection screens.
If I just start the game normally, there is no issue.
If I just loop the title, menu, then character selection screens back and forth for a while (40-50 times),
it would cause out of memory. I know that no one would be crazy enough to loop the screens back and forth like this,
but still it should not be out of memory if it was coded correctly.
Furthermore, if I start the game and then quit the game, and repeat the loop above, it causes out of memory alot quicker.
Also, if I don't comment out these 2 functions in the title screen

ClearGlobalArrays();  
SetupArrayLists();

and

ClearGlobalArrays()  in inLevelLoop(),

it causes out of memory alot quicker. It seems like it adds more stuff to the memory instead of removing them when I start looping back and forth , but why?????

Obviously, I didn't code it correctly....
Please any help, advises, comments to help me with better coding/route/understanding, would be greatly appreciated

I have one game at 1080, i tested 4k, 1080 and inbetweens, settled for 720p now , try sequence with 2 frames.
Transparency will eat ton of CPU processing.

Openbor "can" handle even over 9000p , so DC was right in theory - in practice the game will run until you start adding effects - it will start losing fps even on GPU from the future.
So you will get like 15fps and what kind of experience is that - which is why idisagree with DC on this.
Runs ? Yes , but is it managable to build a game with that resolution ?

Not really , maybe if you have only 1 bg/fglayer, not many effects, then maybe. 1080p isnt that demanding.But "thousands of high resolutions" is just a theory.

There arent many people who did hires games with openbor, im one of them and i dont know anyone else who did 1080 besides you.

Openbor is not using GPU, im on RTX3090 but still get frame drops with a couple fglayers .

Always test ahead before diving and spending time creating big assets.

Id say try to test your sequences in game, on stage to see if youll get performance drops.Try with 10 frames, try with 2 frames.
You will get to the core of the problem fast if You will test like this.

I've been busy and have not worked on my game much lately...
I don't have problems with FRS even with 50 frames animation, but I do have so much issues with memory overloading at 1080p. I have about 1,200 png sprites, and it is overloading the memory. I started to think that this Openbor engine can not handle 1080P :-( I love high resolution games...
DC said 70 of 200k sprites is only 1% of what the engine can handle. However, I have 1,200 of 300kb~400kb sprites and the memory is already overloaded, especially whenever I play webm video which does not make any sense why playing webm video causes memory overloaded?????

How many sprites do you have in your 720P game? Do you have overloading memory problems?
Thank you

1% is hyperbole, however your problem is not the sprite load. It just isn't. Simple math tells us this

Rounding up your sprite size to 500KB each, that means 1,200 sprites comes out to ~586MB uncompressed. Except the engine does trim and compress them, but let's assume it doesn't.

OpenBOR is a 32bit application, meaning it can address ~2GB of RAM. The internal sprite database is likewise indexed with a 32bit signed integer, meaning the hard code limit for sprites is just over 2 billion. So obviously the practical limit is RAM.

At the rate you're going, there's still room for 2,500 more and plenty to spare, and that's assuming absolutely zero memory management and loading everything all at once.

That doesn't account for framerate, hardware RAM limitations, or other issues with your design and workflow, and there are several things that might trigger an OOM error. It isn't your sprite count.

I know my computer is not a gamer computer, but I believe it should be more than enough to run the 1080p games. It is running the official Capcom UMVC3 game no problem at all, no slow down nothing. When you said "framerate", does this mean how many sprites I have per animation or it is the game running framerate?
Can you take a look at my computer and see if it could be the system requirement not met?



Updated:

I just created a new project with only a few scripts and very simple basic stuff in OpenBOR Build 6.3.9.1, but sadly it is still OOM whenever I play Webm.
I do not think this OpenBOR Build 6.3.9.1 works well for 1080P resolution when there are over 1200 png files?
Maybe it requires a gamer computer?

I started Dante with 15 animations, and it worked no problems, but as I added more animations to it, it went OOM. Basically, adding more png files causes the OOM.
