I have experienced zero FPS with standard installation, so I added Optifine, what even at the lowest settings did not make it playable, so I added BetterFPS as well, what did not help either. I set maximum memory to 4 GB and minimum to 1 GB with permgen having 256 MB. I am using MultiMC, latest Optifine and latest BetterFPS and no java arguments. Is there any way to make the game playable? Fastcraft is unavailable for this version of Minecraft. EDIT WITH SOLUTION: Use latest Optifine, but make sure that Smooth FPS option is turned OFF.
I tried what you had suggested, but it did not help at all. I am not using any shaders I know of and Journeymap is disabled.
I had a similar issue on Revelations. In the graphics settings (with optifine installed) search for "animated terrain" or something along those lines, and make sure it is disabled.
Using MyM launcher (fresh install of the pack) with Optifine and disabled Journeymap with 4 GB max RAM and 2 GB min RAM did not solve the issue (I tried with VBO on and off and I set to performance in the Intel HD graphics). I am using Intel HD 3000 with the latest Windows 10 compatible driver. I have noticed that available RAM is not a cause of this problem as you can see on the attached screenshot. I am using the lobby server for testing. Vanilla 1.12 from MyM launcher works fine (59 FPS) at the best settings for performance.
