Hi guys,

Happy New Year!

I love this texture pack (resource pack). It is awesome and I have used this since the begining of the 1.7.10 pack.

Up until recently I used x64 version of this patch on my old GTX 650 2GB video adapter and I got around 40-50 FPS which is expected.

However, when I upgraded my PC with MSI 1070 gaming X 8G I started to have issues. Not only the FPS is the same on x64 resource pack, but in 128 I barely get 20 FPS.

Here is what I have done so far:
Did a clean re-install of nVidia drivers
Reinstalled OS (I was on windows 7 and it was about time to move forward). I did a clean install with formatting the drive.
I updated both BIOS of my MB and the BIOS of the GPU
I re-installed completely minecraft (including deletion of the .technic folder)
I have the latest drivers
I installed optifine and reset everything to minimum - no success
Without the resource pack on the same modpack I get around 150 FPS and about 4 GB of RAM.
For some unknown reason, I am not able to see that minecraft is using my GPU instead of the IGD
Set the proper GPU to be the default GPU in nVidia Control Panel
Tried Vanilla minecraft with Sphax x512 - worked like a charm on around 120 FPS.
Tried the same resource pack on the 1.7.10 modpack - 20 FPS (seems like I am destined to stay on 20 FPS).
Disiabled some resource demanding settings as anti aliasing and anisotropic filtering from nVidia Control panel, vSync is off in Minecraft as well as in the control panel.
Prerendered frames set to 1
I disabled the step-threading, thinking that the CPU might be botlenecking the GPU, which turned out to not be true.
Playing in gaming mode on high performance settings on the PC.

Also to let you know that other games, which are more GPU demanding are doing very well - No Man's sky on ultra settings - around 150 fps with vsync off and steady 60 fps with vsync on - no drops noticed.

I don't GTA to test it, but the benchmarks I did gave me farely good results, leading me to think the problem is software related rather than hardware.

Attached is the DXdiag for your referrence.

I will be very happy if someone can help out with this thing.
Don't spare me, I know my way around PC's since 1996 :), so any suggestions are welcome.

You appear to have done everything already, really...

A good card means little to Minecraft. It's not always going to work well, it's not a very good engine.

When you deleted your .technic folder did that include your saves?

Are you using any particularly hungry mods (most biome changing mods can kill FPS as they paint the world)? Have you tried FastCraft? Have you tried turning animations off in Optifine?

Have you tried running a server on a different PC and connected to that?

Hi HanFox,

Thank you for your reply.

When I deleted the folder the saves were there, yes. But, I had them backed up, so that is not a concern.
I used optifine and tweked the settings around and still no effect. No matter what settings - high or low demanding settings, the avergae FPS is 20, peaking at 24 and dropping down to 1 sometimes.
That is why I think there is a bug in the x128 patch for the 1.7.10 pack.
I tried x128 pack without the patch and the FPS is averaging at 300. I tried with x512 without the patch as well and still getting 240-250 fps which is more than enough.
However, the moment I select the x128 resource pack with x128 patch for 1.7.10 pack, the FPS drops.

Curiosly enough, when I use x64 resource pack with x64 patch for 1.7.10, I get around 150 FPS.

I'm sure I am not the only one on this, since I have been reading forums for two weeks (even got to the second page in Google :D) and found no solution for me. I will be grateful if anyone has the same issue and share a solution, since I looooove the sphax resource pack and I want it to be as high res as possible.

It's difficult to have "bugs" in images... unless you can find some that are oversized or corrupt I doubt the patch is really at fault.

It's not too weird to have a drop when using 128x over 64x just because Minecraft does a lot work moving textures via the CPU, to RAM, then VRAM.

All the animations and entities (mobs, etc.) are loaded as you see them. If you have a lot of animations it can kill FPS quite quickly.

You could try turning animations off (CoFHTweaks can force them off... I'm not sure if that's a different method than using Optifine to disable them).

There really is no magic bullet for this. Having a beast of a PC means nothing to Minecraft.

Thanks, mate.

It does make sence.
But what puzles me is that when I use x512 resource pack, it goes up to 250 FPS and with x128 without the patch, averaging at 300. So I guess it is something weird that I couldn't find.

Thanks once again.
Cheers
