Minecraft laggs or strange fps drops?

^^

Maybe this is not the right platform, but I will try my question anyway. XD

So here are the details: I've had "weird" fps drops in Minecraft for about a month now. However, this only happens when I open boxes or with other interaction or quickly turn around, as I said, I don't know why. This "lag" then lasts at 5-1 fps for about 1-5 minutes. Then it's gone again and if you do the same thing again, it's back. I didn't mess around with the settings or the like. My system is pretty old (i5 2540m and the good old HD Graphics 3000: D), but Minecraft should still pack it. I never had this problem before, just like I said until a month ago.

I have also often checked whether CPu or similar. Throttlet… None. I don't know how to help myself anymore, drivers should all be up to date, I've already done everything, nothing helps.

Oh yes, I use Optifine 1.15.2 pre15 if that helps someone. It's not the server either, although these laggs only happen on a single server, which is pretty strange, but there are also some plugins and quite a bit to load on the server, so yes. XD

So thanks in advance for answers and I hope someone can help me! ^^

Edit: I just tested whether there are such weird drops at Vanilla. Is there. So it's not up to Optifine. I have no idea what triggers it and how it could happen. Osd doesn't show anything "questionable" either.

It is at 1.15. Everything from 1.12 is garbage in terms of performance. Do the other versions as well as 1.15 work normally in single player? I have problems with a Ryzen 1600x and 16GB 3200Mhz RAM in 1.15 (without opti). Have you allocated enough RAM to Minecaft?

Optifine for 1.15 is still in beta, which is why the Optifine client may have an error. But if it is only on one server, then I think that there has been some update that pulls FPS

The other versions under 1.12 are all going well, I assigned Minecraft 4GB Ram, but could increase that, but should be enough, I guess. Minecraft generally performs a lot more than it should, Java is… XD But thanks for your answer! ^^

I already thought about Optifine, as soon as the official version has been released, I will write in here again whether the error has been fixed. As for the server, that shouldn't be the problem, I think, because nobody but me has the problem, I don't know who uses Optifine Pre, but I strongly refrain from dropping to the server push, also there have been no really big updates lately that could cause this. ^^ Thanks for your answer!

But should be enough, I think. Minecraft generally performs much better than it should, it is Java… XD

Yes 4GB are enough. Minecraft is badly optimized, but from 1.12 everything is BAD optimized. Do you understand? You have to wait for the release of Optifine… You can follow it on Twitter. The developer is almost done.

But thank you for your reply!

With pleasure.

Mojang should get a good performance update
