Good day!

I have recently installed 1.17.1 and was hyped to play it. But I discovered that I have have a major drop in performance even though my system hasn't got any issues...

What I did was install optifine to actually reduce these drops but I had no luck in 1.17.1

I compared 1.14.4, 1.16.5 and 1.17.1 to see where it goes wrong, and lose performance...

I did a couple of tests in this order:

1.14.4 (Before the optimization update in 1.15)

Made a new instance of 1.14.4:  FPS = 318 on 32 Render Distance

Made a new instance of 1.14.4 with optifine:  FPS = 358 on 32 Render Distance

Used SUES Renewed on 1.14.4 and got around 150 Fps on 32 Render Distance

Conclusion: No problems with 1.14.4...

1.16.5

Made a new instance of 1.16.5:  FPS = 287 on 32 Render Distance

Made a new instance of 1.16.5 with optifine:  FPS = 312 on 32 Render Distance

Used SUES Renewed on 1.16.5 and got around 97 Fps on 32 Render Distance

Conclusion: Some minor drops in performance even though it makes no sense because there was an earlier Optimization Update in 1.15?

1.17.1:

Made a new instance of 1.17.1:  FPS = 64 on 32 Render Distance

Made a new instance of 1.14.4 with optifine:  FPS = 73 on 32 Render Distance

Used SUES Renewed on 1.14.4 and got around 43 Fps on 32 Render Distance

Conclusion: 1.17.1 has a huge drop in performance even when I was running on 10 render Distance I only got around 94 Fps while in 1.14.4 I got around 432 Fps running on 10 render Distance

All Tests were run with the same settings, on the same word seed and all background programs were shut down. There couldn't have been anything that could mess with the 1.17.1 test.

Please notice this Issue and please tell me if someone has a fix for it?
