Hey guys I am getting like 40fps-1fps when recording with fraps in 1.4 with Low render Before i updated I used to get like 100fps with fraps on far+64 This makes noteblock song recordings impossible. I have 0 mods installed other than optifine and I have a gtx 675m so I should run minecraft just fine. I get more fps on bf3 than minecraft...
You Should Probably Inspect your video settings to check if you don't have render distance or anything else which lags out Minecraft on a high level. If Nothing Helps There then try giving Minecraft more space, like more gigabites or megabites. -Hope It Helps, Aphors
