Howdy!
Closing this thread as it’s not been productive. Please remember our code of conduct and intro thread which you can find Here.
We are not currently aware of any outstanding performance issues with the game after the latest patch. Make sure to review our performance troubleshooting guide located Here. If the issue were to continue, please open up a ticket so we can troubleshoot in detail Here.
Note: Please test in a normal melee match to see if the issue occurs. If you only get this issue within custom maps they can utilize a very high level of units on the screen like later stages of Tower Defense maps. Some custom games might be best played with SD graphics to avoid such drops.
Thank you.
