Problem Fps under 20 FPS

[DjCtavia]

Hi guys,
well, sorry for my bad english, but I will resume easly.

I don't play like 2 years on Feed The Beast modpack, since, I have change my graphic card for a 1070gtx, and get more ram. I have no problem on other games.

Like people know, minecraft play on CPU, but it work very well last time I played, same CPU, and still a good one. I don't know why there is this problem, my log console output don't work too, then can't send anything.

Config :

CPU : i7-3820 / 3.60 GHz
Graphic Card : 1070 gtx
RAM : 32 GB ddr3
OS : Windows 10

Thank you !

not certain. maybe try disabling all the fps optimization mods. like fastcraft, betterfps, optifine, etc. some cards react to miss configured mods horribly. also let the game load for a few minutes. looks like a new game. the game tends to lag for me a lot on new games. the game has to do a bunch of stuff at that point. best option, let it load.

Well, I finaly found the problem, and that the RAM. I was thinking last time I played vanilla, with shadder. Then I try minecraft vanilla and get 30 FPS...
After hours of thinking, last thing I add is the RAM...

I don't know why Java do this, I have no trouble with others games, and softwares, that sound weird ?
Some Idea ? Or I remove maybe 8 or 16 Gb on my computer ?

Rather than removing the RAM, try using Java arguments (or RAM allocation tabs in your launcher if applicable) to limit the amount of RAM Java has access to. For 1.7 without shaders/texture packs the sweet spot was around 4G for me.

Already tried, nothing happened...

have you tested the RAM? you have a lot allocated to minecraft. most the other software you use might not press it up that high. i like to set up a usb with YUMI for testing my PCs. there are likely other options out there though.

If your mip-map is set to >0 try setting it to 0. It was recently fixed so that it works correctly and now needs a lot of video RAM for higher settings
