Earlier this year, completely randomly it seems, i suddenly became completely unable to play minecraft without the game lagging to 2-3 frames a second. After checking around, i saw people suggesting a change to 32 bit would fix this- and it did. Forcing minecraft to run through 32-bit java causes it to work completely fine for vanilla.
The problem arises that If i want to do anything memory intensive, from modding to large lag-inducing builds, I need to have 64 bit to increase the memory to minecraft. Allowing minercaft to use up to 4G of memory causes it to lag all the same while i'm on 64 bit, and i'm at my wits end trying to figure out what the problem is any how to fix it.
first of all, it might be useful to see if this is about minecraft/java or your system. have an eye on the task manager while playing. do lack any resources, like having the CPU run at 100%?
if yes, this could be caused by an external program. (nomally) minecraft just doesnt change its mind for seemingly no reason. check if you have programs running in the background (again, use the task manager).
finally, you might want to try tweaking minecraft with optifine, betterfps and whatever else.
also be aware that giving java too much ram can cause issues as well. dont give java much more than it needs.
I've checked task manager and no, nothing else is using any resources (Minecraft uses the most), optifine didn't change anything when i tried installing that either.
Minecraft vanilla runs fine on 32 bit with the 1G default while the 1G default on 64 bit java causes it to lag horribly and be unplayable so it's not an issue of giving too much ram to java either
Same issue for me. Wouldn't call it lag though, game fps takes a huge dive to only 1-3 fps. Then back to normal for a about ~10sec then dive again. MSI Afterburner shows gpu usage drop to zero momentarily when the issue happens.

Does anyone have any advice?

Two different systems, same problem.
System 1- i3 6100, 8gb ram, GTX 750, 250gb ssd. Win10
System 2- i7 6700k, 32gb ram, GTX 980ti, 512gb m.2 ssd, win 10 also.
Both machines are on latest nvidia driver.
All other games work fine
