Does this game use MegaTexture?

Yes, all id tech 5 engine games do, which is also why they are so large.

Of course, it's idTech5 (and you see the textures streaming).

The megatextures remain the same, minus the baked lighting.

Of course baked lighting is how megatextures for Tech5 were designed, so Carmack doesn't seem to consider them megatextures otherwise.

When he's right he's right. Tango didn't play on the strengths of Tech5, in fact they worked with its weakness.

... and if you think horror and atmosphere can't be done with baked lighting, you haven't gone through Dead City enough times

Yes, I'm well aware of what it means for the engine.

But, it doesn't use megatextures in the same way as RAGE or Wolf.
And personally, I love the lighting system they put into The Evil Within... it looks great. It could be a cause of performance issues in the game.

But, I'd say the borked multi-core support would be a bigger culprit of causing performance problems.
The game damn near maxing one core and hardly touching the others isn't good, and is definitely dragging things down.

No doubt the realtime lighting/shading looks amazing, but that could have been achieved a lot easier with another engine and quite possibly, the game could've looked a lot better while performing a lot better as well.

I wasn't aware about the broken multi-core support. That does seem like something that would cause a great deal of the problem.

Perhaps they will try to fix multi-core support in a patch and who knows, we might see some miraculous change.

Yeah, next time you play take a look at your CPU's core usages.

A lot of people are stating that their first core is at 90% or higher, with their remaining cores barely hitting 10%. I checked on mine while playing, same exact thing. And a few friends checked theirs... and noticed the exact same thing.

Also, Win7 users have discovered that the CPU priority for The Evil Within is setting to "Low". If you attempt to change it, you'll notice a performance increase... but it only last for a few seconds before the priority is rest to Low.

Win8 users are stating it's set to Normal for them.

Yep, "jobs_numthreads" is doing nothing. The command is recognized (otherwise it would say it wasn't), but it does nothing.

Definitely needs to get fixed one way or another.
