Hires Images Lag for a while and then stop

[TheGameratorT]

So, I'm using full screen images in PNG format at a resolution of 2160x1080 and downscaling them using HIRES to fit 512x256.
I'm using them in a weapon like this:

FOXY ABCDEFGHIJKLMNOPQRSTUVWXYZ 1 BRIGHT
FOXI ABC 1 BRIGHT
Loop

But when I use the weapon the frames seem to not be loaded and struggle to appear smoothly. Only after getting them to loop 6 times they start to work normally as they should, is there a fix for that?

If I pause the game for 1 minute and continue it starts struggling again.

Also I tried precaching GL textures and didn't solved the problem.

is there a fix for that?

Yes. Don't use 2160x1080 weapon sprites. You're hurling a whole lot of data into your GPU that the engine is probably struggling to do fast enough.
