Minecraft Memory Problem (I Think)

[Cleora]

So. Here it goes.
My computer is absolutely fine with modded minecraft if done right.
Same with my survival 1.13.2 server, even with optifine and a texutrepack.

But with my CosmicPVP v2 client on a 1.7/1.8 supported server; it glitches out when I add a texturepack. And I mean glitch out. https://gyazo.com/856ce5fcbba7368ff10911f3f72e5ef5

I have lots of memory put into minecraft because 1. For modded minecraft.
2. It's my main game.

So the question is, how the hell do I fix it? I love texturepacks and can't pvp without one.
Add me on discord if need be Cleora#6618 - putting the answer in the comments is fine.

Please don't trash thread.
Ps: The texturepack was only 32x and I use to be able to use 500x + packs in the past with the same client and texturepack. It's not the client, I know that because others using it are not having the same problem.

Doesn't work like that, but If you mean delete and reinstall, yes.

No, not the pack. The pack I tried recently was only 32x.
Some are 500x and well, I use to be able to use them.
Now all texturepacks glitch out my client/minecraft
