Dual Core Processor Is Not Detected

[Mouse]

First off, sorry if the title is a little misleading, I didn't know how to word it.

Basically my problem is that I have just install Rainbox Six Vegas (A shooting game that requires half decent graphics for those who aren't interested in games)

What happens is that Vegas runs a test before you play to determine if your system can play the game or not. My computer passes every test, for minimum and recommended settings except for the processor.

The processor is displayed as 2.6 Ghz and the minimum is 3.0 Ghz

My computer is dual-core 2.6Ghz totallying 5.2Ghz if I'm correct. What's wrong with either my PC or the system checker program thingy that Vegas uses?

dual 2.6 doesn't equal 5.2, it equals dual 2.6

go into task manager, performance, how many cores do you see in cpu usage history part?

Does that mean that when a processor says Dual Core 2.2 or whatever, both cores equal 2.2 and it's not 4.4? Because if thats so I was better off with my 3Ghz single core Pentium 4.

Correct

Incorrect :)

1Mhz means 1 cycle, but the number of instructions per cycle is different on intel and amd computers, a pentium 4 has less instructions per cycle than an amd chip of your era, which has less than a core 2 duo.

Can of worms is the phrase

Sorry for multiple posts, 1 finger typing - should see the size of breakfast :)

Okay.... What's the difference?

Because I genuinly beleived my computer was running with 5.2GHz

So based on what you say the Q6600...

[Intel Quad Core Q6600 95Watt G0 Stepping (This is the one that Overclocks) 4 x 2.40Ghz 8Mb Cache 1066 FSB Quad Core Processor]

Is 4 cores that add up to, in total 2.40Ghz?

[Nox]

nope, thats 4 cores all runnning at 2.4

they don't 'add up' but 1 program can run on 1 core, unless the program is multi-threaded, and not many are

OK... I want your internet connection...

Thats fast!

As Nox said that's incorrect. I was running one of those (in fact a 3.4GHZ HT) and the difference between that and my current rig is amazing. Even before the overclock, at stock of 2.66GHZ, the E8200 is miles better. Bear in mind that the new chips, although clocked slower, are far far more efficient at number crunching and hence are quicker overall despite appearing to be lower specced.

That's college for you. So Vegas is correct that my computer doesn't have the power to run it properly.

According to what you say my computer has 2 cores, each running at 2.6GHz. But I do not have the 3GHz that Vegas wants.

[TheTranquilEye]

So I take it that the game refuses to go any further after the check?

Have you checked to see if there's a patch available? If it doesn't want to work with new CPUs then that's going to affect a lot of gamers. I would think that UbiSoft would have addressed this pretty sharpish.

[Mouse]

It still allows the game to play. I was just baffled that it didn't detect all my processing power. But I was wrong about it in the first place.

[TheTranquilEye]

Rainbow 6 Vegas was released in 2006 which was before multicore processors were mainstream. The software probably isn't able to detect a dual core in that case.

As long as the game plays OK, that's the main thing.

I also take it that:
• When I run Vegas. The computer only uses 1 of it's 2 cores.
• If the game supported it, it would be able to use the 2 cores. Together, Totaling 5.2 GHz?

[TheTranquilEye]

Vegas will be utilising one core only but it'll still be significantly faster than your old CPU.

If a program is multi-core enabled, then it will use all available cores. However, not all applications that are supposedly able to do this fully take advantage.

Okay. So is Crysis dual-core capable? Because I don't think that said I had any issues when I installed it.

[TheTranquilEye]

Google is your friend.. :wink:

The Crysis wiki states:

Single core, Dual core, Multi-core and multi-threaded/hyperthreading processors are supported in both 32-bit and 64-bit modes
