Texture pack crashing

[Silvereyes]

Hello I've just downloaded the texture packs and just went to try to use it but everytime I do it works for a bit but if I move the whole minecraft shuts down I thought it was because of me using lunar but I tried the other minecraft launcher I've also recently added alot more ram space so I don't know what's the problem I tried the lowest ones too and still the same

Are you using OptiFine? Which graphics card do you have?
