> Hello. I have been working on a game very well but after time my biggest issue became the bad fps in my game. I have tried using threads to somehow solve my problem. The fps issue is solved when I thread the refresh() function. But then everything is being moved weirdly and chaos happens on my screen. Then I tried running the refresh function without a thread. The chaos problem was solved but then the fps problem faces me again. Can someone please help me? I have no experience and knowledge using the gpu. Thank you very much

Hi. Maybe you could upload the whole code with images etc. to Drive or Github to see what’s going on.

Hi. Unfortunately I can’t do it on Github. If I upload the whole code then no one will understand anything because my code is all messed up. Everything that is being displayed on the screen is only written in my refresh() function

 ![Screenshot_20220715_131919_com.huawei.himovie.overseas](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/2/1/21630ea2dec3202dbd756eb3043dcb987f01f04b.jpeg)

Here is an image of my problem.

a few things

- what is pause() doin’?
- never use image() with 5 parameters. Instead resize() it in setup() once and for all and then use image() with 3 parameters
- thread is not supposed to be started throughout! Only once in setup()

I commented pause out because it is a work in progress. Is it bad using image() with 5 parameters? Why?

pause() sounds bad; it sounds like delay

5 parameters let processing resize the image which is very time consuming; and it does so not once but every time, 60 times per second

But the thread() thing is even worse imho

I changed the code before. I removed all threads. I use images with different size so scaling them in setup wont do much I guess. Is it really a big difference to use 3 parameters instead of 5? When I use images with different height then I guess I will have to scale them differently anyway

I don’t agree. You can scale them individually in setup(). Or do you mean one image changes its size during the game?

> [@Coder1](#):

Yes, it is.

But test it yourself, when it’s fast enough for you, good. I am happy to drop my point.
