Yes, but issue is not in Optifine 
RX 470 + Win10 + Minecraft 1.7.10 = 60 FPS
RX 470 + Win10 + Minecraft 1.7.10 + GT6 = 2 FPS
On Kubuntu 18.4 it was better(18-44 FPS) but the game still freezes.
Of course, i’ve found the solution: Play Minecraft 1.12.2 + GT5 = 284 FPS
But there’re a big difference beetween GT5 and GT6. And GT6 is more preferable)
As i think, and judging by OvermindDL1 conclusion, MC 1.7.10 can’t work as fine as newer versions on Radeon 400/500 series.
Do you have plans to make GT6 for newer versions of Minecraft ?
