I love what i can do if it worked. It doesnt work that well with advanced video cards. On my laptop it runs great. But anything fancy and it just cant handle it.
I'm using an NVidia GeForce 680 on my main system, and it runs perfectly fine. My AMD Radeon HD 7800 has no issues with it, either. The NVidia GeForce 6800m in my seven year old laptop requires it to be able to play vanilla (otherwise FPS is in the single digits at all times).
I doubt it is an issue of "advanced video cards".
what you mean how it changes the colour ever so slightly? Oh the horror! The disgrace of it! Choice between that little impactless glitch with 30fps or not having that glitch and 5fp... hmmm wonder which wins...
Maybe there is another glitch than that involved, eh?
LOL no it makes my chests spin. This is only on my advanced pc. On my laptop it works great. I have messaged him about it and yeah... *shrugs*
What version of OptiFine did you use? Have you tried the current version? And don't just answer offhand, actually go check. If you cannot answer the first question accurately, you cannot answer the second question without actively downloading the latest version and giving it a shot.
To confirm, I've never seen an iron chest spin with optifine, or sans optifine.
