Lord of the Figs isnt anything too out of the ordinary, the goal of the Modpack was to make Minecraft a rpg game with a medival vibe. Mods that was used to change the game to feel more like that Include mods Like book of Dragons, Iron's Spells 'n Spellbooks, Terralith, Medival Music[Forge/Fabric] and Much more!

On a preformance scale I wouldnt say it is too demanding compared to other Modpacks.

Without shaders I would say atleast a gtx 960/R9 380 and a i7 3770k/i5 6600k should work well but anything with less horsepower could work well too.

With shaders I would say you should have atleast a rtx 3050/RX vega 56 and a i7 8700k/Ryzen 5 2600 but preferably better. I would recommend a more powerful gpu and cpu than those if you want 100+ fps with shaders, something like a rtx 4060/rtx 5060 or better and any modern cpu should and would do wonders for you in most games and scenarios.

For ram I would recommend giving Minecraft atleast 4gb of memory but preferably 5 to 6gb but if less works, go with that if you really need it for something else, and ofcourse the other way around, dont be cheap with it if you have the resourses for more. anything above 7gb is probably not necesary and just overkill.

AND remember to take all of those recommendations with a grain of salt, I havent fully tested it across many computers so I cant say for chure what works and what doesnt, that is just a rough guess based on what I know from playing with my friends.

Much love, hope you have fun playing!

Wish you all a great day <3
