Enabling mutlicore support for TF2

[[fr31ns]Karrde]

lost fps and had a lot of chugging.

Why would you need this really?  I mean, source isn't very resource demanding in reguards to CPU's, and if you already have a dual/quad core chances are you can run TF2 just fine in the CPU department.

Well I have a X2 4200+, and TF2 ALWAYS used the entirety of a single core. The fact that enabling this has improved my performance a lot just goes to show you that a ~1.1GHz core is not necessarily enough to run TF2. And yes, orange box games actually ARE very cpu intensive.

Actually, Duck, the speed is not halved between the two cores. That'd be extremely silly. <.< So it's a full 2.2GHz per core, but it IS unfortunately still not exactly the most optimal for the Source engine.

Oh god! All my 16-cpu, quad core servers! They're all like.... 600mhz then!

Sounds like it'd be better than the old Poweredge I got from my dad's back yard, then. >.> *dual-800MHz-CPU setup*

You know what's weird is that I read this comment after an article saying that Intel was working on something big involving cramming a shit load of old pentiums on a board and using it as a multipurpose processor that could do graphics among other things.  It is supposed to revolutionize the industry, but you know they always say that and as of yet I haven't felt revolted.

That would be a horrible idea, the problem is that video card processors (GPUs) have circuitry optimized for performing matrix calculations, which is mostly what graphics are. Standard computer CPUs are NOT optimized for such calculations, just taking a bunch of old Pentium style processors and trying to make a graphics cluster out of them would suck.

Heck even their new little baby, the cell, sucks at graphics calculations, the PS3 had to have a Nvidia 7900 GPU stuck in sometime in mid development when they realized that the Cell wouldn't have the muscle for graphics.

Yea there was more to it than I am remembering.  They said it is possible it could do great for graphics but it would need to be tested.

Not to mention the power requirements. Huge core die-sizes and the heat produced!

[ktj]

Nice, I didn't know about this

[at0m]

I don't use multicore because i want to leave a proc open for my background processes to use (XChat, Vent, iTunes, Azureus, pr0n vids) while TF2 hogs the other one. That way, my game doesn't skip if my video player changes tracks or a download finishes or something.

Thanks for the info, though!

Quadcore ftw. 8)

[Loqutus]

The code in the first post gives me a higher framerate with no downside whatsoever.

Thanks!

Well you see, the plan is to use the excess heat to power your water heater thus balancing out the energy costs of the cpu by saving on water heating. This is actually one of my projects I'm working on, along with the Gerbil powered CPU's. It is hard teaching Gerbils math to do all the calculations though.

Will you implement a unified gerbil architecture on a video card so any given gerbil can execute any shader instruction to comply with GerbilX 10 standards?

Oh, I noticed no real improvement with the multicore instructions in autoexec.  Just stating for statistics.

I've tried twice now, second time after a -autoconfig boot. Both times I got horrible stutter, jaggies and a massive drop in FPS 

[chronomaster]

Hmm... Technically, TF2 crashes when I attempt to quit the game. Maybe I should try this to see what happens. :V

I'm getting the stutter effect too. Really disorienting. Also, models flash in and out. Haven't tried it on an active server though.

I might as well try this out and see if I can squeeze a few more fps out of my little integrated laptop graphics card.

LOL

Good luck with that though, seriously. Hope it helps.

[/quote]Surprisingly, it seems like it helps quite a bit.
Then again, I only tested it on an empty server, so...>_>
But it seemed stable enough.

it happens the same to me, everytime i close TF2 a message of hl2.exe crashing appears
