Thank you for the tips. I used both settings but from my testing the initial poolsize value in BaseEngine.ini had the biggest impact. I ended up pushing it to 10000 since my card has 10GB of VRAM. I’m not sure the logic is correct here, because I’m not even sure the value is supposed to be in MB but it seems to be working.
Would there be any disadvantage to unlimit it by putting it to 99999 ? I tried setting 0 as a value but it used less VRAM available than when I set it to 10000.
I’m mostly concerned about stability and performance. All in all I feel like we are just tinkering with settings that should be properly explained by a UE dev somewhere so that there are less guessing games.
