Frequently Asked Questions (FAQs)
Does this shader require an RTX GPU?
No. MemeTX simulates RTX-style graphics using shader techniques. While a strong GPU is recommended, RTX hardware is not required.
Is this compatible with OptiFine?
Yes. You must install OptiFine first. Then, place the MemeTX shader ZIP file into your .minecraft/shaderpacks
folder and activate it in the Shaders menu.
How is this different from SEUS PTGI or BSL shaders?
MemeTX is designed to closely mimic RTX visuals from Minecraft Bedrock. It emphasizes reflective materials, sharp lighting transitions, and glowing blocks to match the RTX style.
What kind of performance can I expect?
This shader is graphics-intensive. A modern mid- to high-tier GPU is recommended (GTX 1660, RTX 2060 or better). Lower-end systems may struggle with stable frame rates.
Can I use this with modpacks?
Yes, as long as the modpack supports OptiFine. Some mods may affect visual performance or render compatibility, so test before using in large setups.
