Multimc Optifine Without Forge: A Comprehensive Guide

When it comes to running Minecraft with OptiFine and without Forge, there are a few key things to keep in mind. First, make sure you're using a fairly recent graphics driver version, as older versions may cause issues that are no longer taken into account by Shaderpack developers.

One of the most important considerations is GPU compatibility. See the GPU column in the Shaderpacks page for specifics. While GNU/Linux and macOS users may experience less universal compatibility due to low market share and arcane driver restrictions, Windows users should have no issues running most if not all packs.

In terms of system requirements, it's worth noting that you don't need to change your allocated RAM amount to accommodate OptiFine. However, if you wish to run high-resolution resource packs, be aware that 32GB will be required for the highest-end configurations, along with around 10GB of VRAM. Additionally, some resource packs can take advantage of advanced features (called PBR materials) which can approximately triple your RAM usage.

Shaderpacks themselves have little effect on RAM, but they do have a significant impact on GPU performance. The Shaderpacks page lists a rough performance category for each pack, ranging from Potato (which should run even on integrated GPUs several generations old) to Extreme (which require a beefy high-end GPU to even be playable at 1080p).

Due to the sheer variety of available shaderpacks, there is no single system requirement. Any relatively modern CPU will be able to handle these, though for less powerful CPUs like those found in laptops, lowering render distance may be required for playable framerates.

Finally, it's worth noting that shaderpacks have little impact on the CPU aside from one effect: dynamic shadowmapping, which requires the world to be rendered twice. Overall, with a modern GPU and reasonable system requirements, you should be able to run OptiFine without Forge with ease.
