Alright... Drawing fast was a thing, true, not sure why this thing was lagging tho, cause from my understanding it is the same as drawing small ones in terms of memory/time complexity, so idk xd But still thanks :3
I went back to try, it seems it is the explosion that triggers the lag. I draw the big lines, put an explosive on some lines and when the projectile reaches the end, it freezes/lags
