Multi Core and Multi Threading : How work this stuff ?

[Silica Gel: Do Not Eat]

With Windows XP if you upgrade from a single core to a dual core you may need to reinstall the OS to see both cores.
When you do CTRL ALT Delete and Choose Performance do you see two graphs for CPU usage (one for each core?)

Nexuiz should use openmp to speed up on multi-core processors

For anyone working in a large organisation who has a dual/quad core CPU, try this. It's amazing the number of companies whose IT departments somehow justify buying more cores and then stick the same uniprocessor kernel on every system.

I already had a core2duo CPU quite early and in the first days I had to assign Nexuiz to one of the two cores manually via task manager to get reasonable performance.

Thanks for the tips! I learn now this OS feature. I will try. But i have to do this all the time i run the thread? Or OS can remember.

Yeah vomit i can see both cores and with firefox 3, norton internet security and task manager (and few autorun proces) running I see CPU are busy for 2-5 % and reading the two graphs seem the first core make almost all the work. This mean not all the sw running is really optimized to work on multi core? Reading Ed post the answer is yes?

what's openmp?

Ty all.

Also SP3 has a Dual Core Hotfix If I remember correctly

Will *easily* allow darkplaces to start multi-proccessing

It must be assured however that a mp support wouldn't result in a disadvantage for all the single core users which I think is still the majority of the players.

IMO Nexuiz runs fast enough on dual core rigs without this feature. Who needs more than 200fps on ultra settings?

Almost all Linux distros build for SMP (typically 8 cores) and it isn't often you see people complaining about that. You could however make it a compile time option to disable SMP, just like the kernel does.

Well I have a quad core at 3GHz, and can't use Ultimate (gefore 9800gt), and I want more fps

I always thought that single core CPUs were phasing out, hell the last I checked most people had Core 2 Duos and half of everybody building a PC right now goes with a Phenom II or (if they have tons of money) the Core I7.
