Bethesda, most embarassing CPU optimization of the decade
 
Quote:

Skyrim was coded in x87 code.

It does not have SSE optimization which has been standard for both AMD and Intel for nearly a decade now. Never-mind the new advanced vector extensions now available. They should have optimized for SSE 4 and AVX... not x87.

This is just a total blunder on Bethesda's part and absolute embarrassment. Unbelievable, I just can't believe they did this. Confounds me.

This is probably among the top reasons why Skyrim only runs on two threads.

I'm not too savvy on alternative architectures but what uses x87? Is it an extension of x86? Furthermore, would skyrim benefit from using more than two threads? I mean significantly benefit? Does it not run really well as is?

huge difference in Markath...which must've been cpu limited before....now it's smooth as butter, no chop to be found.

x87 is just the standard FPU without any SIMD FP acceleration. It's 'sort of' like having the game run in software mode rather than hardware mode.

x87 was actually a separate FPU (math) chip as far back as the 386. Some 486's didn't have them either or they were disabled... Can't remember offhand.

Your looking at 30-40% increase in performance.

Ya I am using this now and there is a very noticeable difference in towns. Thanks to the modders! :D

OMG THEY SHOULD ALL BE LINED UP AND SHOT. THEN WE WILL TORTURE THEM TO DEATH. AFTER THAT WE WILL KILL THEM, THEN REVIVE THEM AND KILL THEM TO DEATH AGAIN. AFTER THAT WE WILL SEND THEM TO DETROIT WITH A LOT OF BLING BLING AROUND THEIR NECKS.

WTF! stfu and play the game. I can't believe the stuff you guys cry about.

It's posts like this that make devs go down CliffyB road.

OH! I am familiar with the math co-processor back in the day! Been so long I didn't even consider that. :lol: :o

Wow... this seems like a rediculously major over sight on their part.

Yeah, now that I know what they're referring to I can see the increase. :)
