So as the thread I was posting in was marked resolved and closed even though I was still having issues I shall have to start again.

Minecraft 1.8, amazing lag issues on single player.

i will be mining then freeze for 5 seconds, there's no pattern to what activity i am doing, where I am, what world i am in or anything.

When i am not lagging I am running at 75fps easily enough, MC isnt using even half of the memory that the system has allocated for it but I am still getting this issue.

this is happening for all the various versions of 1.8.

just walking down a 1 wide tunnel is lagging beyond belief, 1.8 is completely lost to me until there is a fix for this

What are your computer specs, and are there any error messages in the Launcher log? If you give me this info, I can help you.

Intel core 2 duo CPU, 3Ghz,
4Gb DDR3 Ram
Graphics card is as I recall an ATI Radeon HD 4800 series.
I run Windows 7 64 bit

No error messages appearing in the log that I can see.

Just turn off vsync, hope this helps

VSYNC just regulates frame rate... That wont help at all. If you have VBO's on turn them off. 1.8 also introduced a new vertex buffer May be incompatibility with OpenGL and your drivers.

While ordinarily I would agree with you. 1.8 changed something that made VSYNC have horrible effects for me and others. It depends upon your GPU and driver because it only happens on one of my computers, but when it happens I would call the game unplayable. Turning Vsync off makes that particular problem go away.

For frame rate lag, this may be the case. They are talking about SERVER-SIDE lag, which is the way the server handles vertex buffering. 1.8 introduced a new way to use the buffering while loading chunks, which may or may not use OpenGL depending on the card/drivers.

Since I world size 'locked' my map to 4096 x 4096 with a border 8192, then script walked the map, so it is all generated(16GB region)
I do not have ANY server side issues with my player base, even with 40 mods I get about 34ms for ticks... The ONLY time it really bogs is during land generation, IE in the Nether, so I may script walk that too and it should go away... IMHO.

I humbly submit that this issue is also client side and effects single player, so script walking a set size world should clear it up....

Yeah VBOs are off, VBO off, smooth lighting off 3d anaglyph off, graphics on fast, antialiasing off anisotropic filtering off, even turned all the animations off though it made no difference.

completely unhelpfully the "lagometer" shows the spikes I receive... as white which isnt anything specific on the list.



And as for loading the chunks first i get this while building in my original spawn location, everything around there should have been well and truly created.

Press Shift+F3 and tell me what is the biggest parttition of that pie graph there. That might show me the problem.

No, I"m talking about exactly the kind of lag that the OP described. The game freezes for multiple seconds at a time, in fact while (attempting) to move the game is frozen more than it is not. Turning off VSync instantly makes that problem go away (if it is the same problem). I think it only affected my computer with an ATI GPU. Nvidia was not affected.

I havent used V sync, I think itsbeen set to 120fps most of the time though I have tried tweaking it around but never with the VSync

as for the t F3 chart its primarily game renderer or display update that are the biggest, occasionally with a spike from unspecified that doesnt seem to correspond to a lag spike
