Just thought I'd throw this out here for any quick fix ideas... I've just built a budget PC and minecraft is running really slow I would expect the performance to be much better after reading various reviews of the hardware etc Spec Intel g3258 not tried over clocking yet Amd 260x 1gb 4gb 1600 vengeance ram one stick Corsair cxm430w Windows 8.1 Catalyst latest drivers Installed mine craft and when running into trees etc the GPs can drop to 20-30 and it's really slow and unplayable, even with the video settings pretty low This is at 1920x1200 I would expect the performance to be far better, and I neeto fix this asap so any ideas or advice would be appreciated I'm going to try a reinstall of the os next I'm wondering if my cpu or GPU could be being throttled or something, or if something is defective, surely the power supply would be adequate for this setup
I'd try overclocking first before reinstalling. The reviews suggest you get the best from that CPU by overclocking it. I'd monitor your CPU and GPU temps as well to make sure they're not throttling due to heat. The PSU wouldn't cause throttling, it'd shut down if there wasn't enough power. I've assumed you've installed the latest drivers for the chipset as well as the GPU.
Everything is running very cool, about 40 in the cpu with stock cooler and 30 on the GPU Not tried chipset drivers yet, will give that a go
Do you have the Optifine plugin ? It really helps with Minecraft: http://minecraftsix.com/optifine-hd-mod/
Heard about that, but surely I shouldn't need it to fix my problem, was I wrong to expect such a huge difference in performance with this spec? That is the question on my mind....
Minecraft is pretty poorly optimized to be honest. Even with my i5 + 8GB + SSD + GTX770 I encounter unexpected slowdown here and there. Recently, I dropped at 2fps because I reached the max memory allocated to the JVM when playing with redstone ... 1GB by default. My opinion, JAVA should be banned for anything needing performances. INFO: My current screen has a resolution of 1280 x 1024, so I shouldn't have this.
I'd say the 4GiB RAM would be the limiting factor with Minecraft, as Guille says, it's a complete memory hog. I'm out of touch with AMD graphics, but is the 260 a low end card? Scratch that, looks like it's an mid range card, only slightly behind a GTX660 in Futuremark.
Try turning off VSync and the OpenGl setting, that bumps up my fps on modded MCs. Also, I believe I remember reading people were getting less performance with MC and Java 8 than 7, but I don't think it was ever a proven thing. Edit: Could be a lack of memory as others have suggested too.
Thanks for all the suggestions, have the day off tomorrow to troubleshoot and get this machine running smoothly. It's a christmas present for my girlfriend's daughter so want to get it all running great before I hand it over. I can try:- updating all drivers adding more RAM from my own machine overclocking the CPU running other games like crisis, battlefield, tomb raider etc reinstalling windows running a few benchmarks Will report back soon...
