I can run and play Tekkit legends no problem but everytime i try and load the 64x Sphax PureBD TL resource pack the game freezes fora second then returns to the main menu screen with the default pack. It's not crashing or anything just not loading in and im not sure why. Does anyone know a solution or have the same problem? When I try to load it in game it crashes, not sure why. I was able to run the same thing on my iMac which has worse specs so im not sure what's going on.
Here are the specs to my computer if it helps
8GB RAM / GTX 970 / AMD FX-4300 (3.8Ghz) / 1TB HDD
