I just made a custom mod pack with the twitch launcher on 12.2. I have about 5 friends who can play it fine, including myself. However, one friend only gets 1-2 FPS, and I'm trying to find out why.
He has a I5-4690K CPU, amd radeon r7 250x for his graphics card, 16GB ram.
This is what I know.
1. It is client side, since it still lags even when he makes a single player world.
2. He can play larger mod packs such as sev tech ages without any problems. He can also play vanilla Minecraft without a problem.
3. He has allocated about 8G of RAM to Minecraft.
4. He has updated java.
5. He has updated his video drivers and its not a dedicated video card problem since he only has one.
6. He has reinstalled the mod pack.
7. When he gives Minecraft high priority on his CPU it goes to 100% and he still gets 1-2 FPS.
8. His memory and GPU usage is around 60%
I feel like has to be something dumb, since he can play other huge mod packs on 12.2 with twitch launcher without a problem and no one else is experiencing this problem.
Id appreciate any suggestions.
