1.19.0 Forge 1.19+ RAM Usage

[Giovani1191]

Hi all!

I’ve wondered if anyone else has seen the same problem recently. Since switching some of my mod packs to 1.19, I’ve noticed that I’ve had to allocate WAY more ram to the mod packs to get them to run correctly. Compared to 1.18 where I usually averaged about 8GB of ram for my biggest packs, I’ve found that since moving to 1.19, I’ve needed to allocate up to 12GB to get the mod packs running.

Has anyone else noticed this? Does anyone have an explanation as to why? I’ve tried multiple versions of 1.19, and multiple versions of Forge. I’ve tried with optioned, without optifine, and with optifine alternatives like sodium/whatever-the-forge-port-is-called. For me it’s not an issue, as I have a beefy pc (Ryzen 9 7900x, 64GB ddr5, RTX3070, etc), but I would like to make some of my old mod packs still playable on middle-end PCs. Anyone got any insights?

I've noticed a bit of a spike, too, but not that much. I'll try to figure out what's wrong next week.
