BingBong Posted December 30, 2012 Share Posted December 30, 2012 This problem has been present ever since the first time I played Tekkit(this is single-player by the way) . For the first 2 or 3 minutes, Tekkit runs okay -around 30 -50fps (80 when I look at the sky). But then suddenly my fps nose dives, going as low as zero, but usually hovers around 10 fps. I really don't get it Now for the memory issues part. Lets say that on the Technic Launcher I select 512MB. Then i press log in. It loads then I click on my world. The world loads and then i press F3. In the top right it says: Used memory: 20% (110MB) of 494MB Allocated memory: 39% (194MB) What is happening and does anyone know a way to fix it? Any help would be much appreciated. System Specs: Microsoft Windows XP Service Pack 3 RAM: 3.5GB Link to comment Share on other sites More sharing options...
Mercalyn Posted December 30, 2012 Share Posted December 30, 2012 It could very well be that you're 2 operating systems behind. I don't like Windows at all, so I don't vouch for it. On the other hand, Linux has problems with ATI. You could look up how to use Java with more memory. In Win7 you would go to Control panel, Java, Java, view, user, in runtime parameters click ADD and put in "-Xms1024M -Xmx2048M" I would double the default amount, I tripled mine. You can also do -Xms2G -Xmx3G Link to comment Share on other sites More sharing options...
BingBong Posted December 30, 2012 Author Share Posted December 30, 2012 Wait, wait, hold up. What's the default amount? EDIT: Just wondering, but is there a correlation between the low fps and the strange memory issue? DOUBLE EDIT: Didn't work Link to comment Share on other sites More sharing options...
Mercalyn Posted December 31, 2012 Share Posted December 31, 2012 I'm out of ideas then! Can you run vanilla Minecraft at normal FPS? Link to comment Share on other sites More sharing options...
BingBong Posted January 1, 2013 Author Share Posted January 1, 2013 Apart from a few lag spikes here and there, normal vanilla minecraft runs fine, hovering around 30 or 40 fps, sometimes reaching 50 fps. Link to comment Share on other sites More sharing options...
Chefsbrian Posted January 1, 2013 Share Posted January 1, 2013 I had a similar issue running 32-bit Vista, I tried all the fixes and suggestions to get minecraft to adopt a higher allocated memory to no avail. I finally solved the issue by going to windows 7 64 bit. The Launcher and Java both seem to like 64 bit systems much better now, and my game runs with 3gb allocated. Unfortunately, it might just be best to bite the bullet and get a newer OS.... SP3 was launched back in 2008, and the core of the system all the way back in 2001.

BingBong Posted January 1, 2013 Author Share Posted January 1, 2013 I believe that upgrading my OS is more like a last-ditch attempt, so I would rather try every other option, then either do as you said or try to play tekkit with the lag. Also, i really don't like Windows 7 Link to comment Share on other sites More sharing options...
Mercalyn Posted January 2, 2013 Share Posted January 2, 2013 Then try Linux. Link to comment Share on other sites More sharing options...
BingBong Posted January 2, 2013 Author Share Posted January 2, 2013 Look, I don't want to upgrade my OS Any other ideas? EDIT: OK, the problem has changed a bit. Now, what happens instead is that the first 2 or 3 minutes are fine with no lag spikes. However after that previous good spell, instead of the constant lag i described earlier, the fps constantly changes and there are many lag spikes. The worst of the lag spike come from spinning (looking) around. Other major lag spikes include going into my inventory, clicking on a crafting table, chest or anything that has an interface.

Mercalyn Posted January 3, 2013 Share Posted January 3, 2013 I reload my OS every 6 months or so(it can't stay status quo forever!) Anyways, do the lag spikes happen on SSP too? Link to comment Share on other sites More sharing options...
BingBong Posted January 3, 2013 Author Share Posted January 3, 2013 If you mean technic SSP, then yes, the lagspikes are still present Link to comment Share on other sites More sharing options...
Teraku Posted January 3, 2013 Share Posted January 3, 2013 I reload my OS every 6 months or so(it can't stay status quo forever!) Anyways, do the lag spikes happen on SSP too? If it's necessary every 6 months, then I believe the problem is between chair and keyboard. Link to comment Share on other sites More sharing options...

Mercalyn Posted January 4, 2013 Share Posted January 4, 2013 If it's necessary every 6 months, then I believe the problem is between chair and keyboard. Yeah, I load it with a lot of games and programs. All with the knowledge that it'll be all okay in 6 months :D Link to comment Share on other sites More sharing options...

Mercalyn Posted January 4, 2013 Share Posted January 4, 2013 Hello? Sorry, off topic a lil' there. You've tried the obvious things right? Adv OpenGL ON, Smooth lighting OFF, Render distance: Normal, Performance: Max FPS & Graphics: Fast? Link to comment Share on other sites More sharing options...
BingBong Posted January 4, 2013 Author Share Posted January 4, 2013 Yep, I've tried all of those things, except Advanced OpenGL On. I'm about to try that now. EDIT: Advanced OpenGL On didn't work BUT I think I've found out something: I think my fps issues are coming from problems with rendering. However changing the render distance does not do much. Tiny does increase fps but lag spikes are still present when i turn around on the spot DOUBLE EDIT: Yep, definitely coming from rendering Link to comment Share on other sites More sharing options...

Teraku Posted January 9, 2013 Share Posted January 9, 2013 Increase the amount of RAM. Also, Technic will not run well on 32-bit Java. I'd say install 64-bit, but you have a 32-bit OS. If increasing the amount of RAM and installing Optifine doesn't help, then you're out of luck. Link to comment Share on other sites More sharing options...
BingBong Posted January 9, 2013 Author Share Posted January 9, 2013 When you say installing OptiFine, do you getting a different OptiFine than the one that comes with the technic launcher? Also, another weird thing just happened. I allocated 1536mb to tekkit, but in-game on the debug screen the memory was only 247mb. Any ideas about that?

Teraku Posted January 9, 2013 Share Posted January 9, 2013 Allocating 1,5 GB only means the maximum increases to that. The initial heap size is something different. Link to comment Share on other sites More sharing options...
