Hello,
I haven't played Minecraft since 1.6.4 because I waited months for all my mods being updated to 1.7.10.
Now I wanted to play it, but I got massive lags which make the game unplayable.
I'm running Minecraft 1.7.10 with the current recommended Forge version 1230. I also tried earlier and newer versions, none with success.
I got two machines I tested MC on.
My machine:
Windows 8.1 x64
i5-2500K @ 4.5 Ghz (Quad)
AMD Radeon R9 290 (4GB)
8 GB DDR3 RAM
Java 8 (latest) JRE (Yes, I used latest Java 7 JRE for the below mentioned tests, but this doesn't change anything - I tried 8 later)
Reference machine:
Windows 8.1 x64
Celereon G1620 2 x 2.70 Ghz
GeForce GTX 560 Ti (2GB)
4 GB DDR3 RAM
Now here two screenshots (using Forge & Optifine) with activated Profiler & Lag-O-Meter.
My machine:
Reference machine:
As you can see, with nearly 80 Mods activated, Minecraft runs perfectly smooth and fluid on the Reference machine, which is indeed A LOT weaker when it comes to CPU-Performance. On my machine I get terrible lags and the tick times are incredibly high. I mean take a close look at the Profiler. On my machine most of the time is used for tick updates while on the reference most is used for rendering. I also get 30 FPS less than on the reference.
Meanwhile I can definetly say it's Forge's fault. I tried Vanilla Minecraft on my machine and it runs smooth without the tiniest lag @ 80 FPS. When using Forge without a single mod, I get all these stutters and lags. The tick times increase to double the value with all mods activated.
Please don't tell me my system can't handle Minecraft with 80 Mods. That reference machines does it with ease, so nope. I got told this way too often. It's definetly not my hardware. And moreover then Vanilla wouldn't run perfectly here.
Lags appear all the time, but just short ones. As soon as it comes to generating new Chunks, then really hefty lags set in (that's when a lot of warnings appear in the log, see below). Another thing is, though MC runs at 30 FPS on my machine (with mods) it feels not fluid playing it. As the lag-o-meter shows, all few ticks appear to be a more intense lag which cause this behaviour as 30 FPS should appear to be fluid - but it stutters when moving around, simply micro lags. Really strong lags also appear when opening the UI (chests for example).
So as you guys request, here the FML log and the client log (which shows warnings "Clientside chunk ticking took 100+ ms"):
I really hope you guys can help me, as every other person hasn't managed to do so. I really want to play MC again, but not without mods.
Maybe the creators themselves know what could cause this behaviour.
Thanks for your help,
