I know that OptiFine_1.6.2_HD_U_B5 is a pre-release but I thought you would like to take a look at this error. I get it when I try to start MC, it immediately crashes to the launcher error screen.
You have forgotten to add "-Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true" in the JVM Arguments (Java Parameters).

Any idea what I'm doing wrong?
Try reinstalling, it looks like you deleted the other files in the minecraft.jar
You can also try using one of the no-.jar-modifying methods
I play a lot of heavilly modded minecraft on an awesome computer. Optifine used to actually decrease my FPS by as much as 20 FPS.
However, I now am hosting servers on it (a few for small groups of people who dont really use it much, and one as a minor server for my server group TMD), using Visual Studio, and many other things so it had severely harmed my minecraft's preformance- decreasing from 500 FPS to as low as 30 at some times. Using optifine I can get 200 FPS again (not as good but MASSIVE difference)! (And MC takes a bit less away from the servers now too- not that it took much ever). Its a win win for everybody.
Keep it up. I may make a server optimizing mod myself- thats something everybody needs.

I'm hoping to become a Minecraft Forums moderator! +1 my helpful comments so I can know what a good post is!
I have a huge problem with OptiFine. Whenever I install this, and enter the game, very little time after (many times, this happens instantly), the game, and my whole PC freezes, and after a while, the screen goes black, and nothing else happens.
My monitor doesn't even give me a "No Signal" message. The screen is just like it was receiving a black signal. The PC keeps running. I had two rare cases (in like 20 times this has happened), where after a couple of minutes, it would report "The video driver has recovered". Minecraft would crashed, but the rest of my system would restore.
My rig is:
CPU: Intel Core i5 750
GPU: ATI Radeon 4770 HD
Motherboard: ASUS P7P55D-E
If there's any other information that you think is necessary to solve my problem, or some troubleshooting mechanic, tell me and I'll be glad to present such information.
P.S.: I've also had this problem for quite a long time. For a year or more. I've went through many re-installations of my OS, many different versions of my graphical drivers. And they always had this problem. Only on the very first times I used OptiFine (The first few versions), I don't recall having any problems.
OK, concerning the random mob textures, it appears that in the resource pack you need to create a folder called "mcpatcher" and replicate the mob folder file structure within that.
I don't have mcpatcher installed, but it still works, which means that Optifine is searching for this folder?
Sp614x, Can you fix this mc bug? https://mojang.atlassian.net/browse/MC-10323 Basically its a enchanted item glow bug when close up, it kills FPS down to 1-3, Apparantly its fixed with BFG.class replacement i found online but my AV Says its a virus, scanned online and its a virus, so could you like... work your magic and fix it?
(And if you cant, maybe add some way to remove the enchanted glow & colour client side?)
