How Many Dual Core Users ??

[Prophet_169th]

Since LO doesnt support it...... virtually no benefit.

i just joined the dual core club, its very goodly.

Me too. The AMD price slash is just too good to pass.

I have an E6300

Well, I guess I entered the dual core club over the weekend. I replaced my good old AMD 64 3200+ with a new AMD 4600+ X2.

 

By the way, I suggest to moderators to un-stick this thread because it is almost a year old. I am sure by now, there is many more dual cores out there.

[Allochtoon]

I run a AM2 3800+ now, should i install windows xp 64 bit or the normal one? (does lomac have problems with it?)

 

I can't seem to search properly in the forum.

[Pilotasso]

Im goin to skip Dual core entirely. I have no other game to buy in the near future so I will keep this one till then.

 

Im following quad cores technology and may upgrade when prices are fair.

[Allochtoon]

Should i run xp 64 bit, or stick with 32bit? I read somewhere about a program to point each processor to a different process, where can i find that?

I read in another post that some people have problems with xp 64 bit (not many people seem to use it), so you might want to stick with 32-bit. The program you're referring to is called procaff and you can find it here :

 

http://www.stefan-kuhr.de/procaff/main.php3

 

Use as follows :

- Copy procaff.exe in C:\Windows\

- You have to edit your shortcut as follows :

-> rightclick on your lockon-shortcut and select Properties

-> change the target to #C:\WINDOWS\procaff.exe /run 2 "C:\Program Files\Lock On\lockon.exe"# (remove the #, but keep the double quotes)

-> keep Start in as : "C:\Program Files\Lock On" (keep the double quotes)

 

Procaff makes sure that Lockon.exe is started on the second processor (in Task Manager => CPU 1, the first processor = CPU 0).

 

Kind regards

There is ZERO advantages of going to 64 bit OS right now. All your gonna be is a home lab rat. Good luck. ;)

[Shaman]

Quad core is almost here and Lock On still haven't been patched to support multiple cores, damn.

Thanks man :)

how hard would it be to do that?

[zorlac]

how hard would it be to do that?

 

Incredibly hard. Its not just a simple case of patching a bit of code, it would be easier to rewrite it from scratch to support multi-core/multi-cpu. The problems that appear when you start running code on seperate cores is vastly more than just twice as difficult. I have been playing (briefly) with multiple threads in the upcoming version of TouchBuddy, and its an absolute nightmare to back-port it to use the multi-core/cpu efficiently.... so I only used it where I really needed it, and even that small routine was a horible horrible few days of coding.

 

You have to ensure that everytime one part of the program access some shared data, that that data is tested to see if it can be locked (or wait until it can), then attempt to lock it (and wait if it cant) then read or write to the shared data, then unlock access to the shared data, so other parts of the code can access it. If you dont lock your shared data, you end up with one part writing while another is reading, and one or the other will obtain an invalid result. You also have to make sure that if you are blocked from access by a lock, you have to wait until you can, or go off and do something else and come back again.

 

Debugging multi-core/cpu code also becomes a bloody nightmare... OK, your code just did something odd.... which part? it might not be the part you think because some of it is running separately, and it might be that part that is crashing. Was it the part that wanted to read some data, or the part that wanted to write to it? if you have more than 2 "threads" going, which one of the multiple threads was it that crashed, and why? if thread #4 crashed, which thread was it that it got upset about, or did it crash all by itself?

 

I am hoping that Tank Killers will be written from the ground up as a multi-core/cpu capable game, but I would be very very suprised if LOBS is multi-cpu/core aware.

I finally joined the Dueal Core club over Christmas. My move was from an old (5 years) AMD Athlon XP1900+ based system to a Intel Cored 2 Duo E6600 based one. The difference in speed, heat, and sound is huge. I'm happy as are games that I simply couldn't play in much detail. No more slide shows. :thumbup:

[Raptor22]

My Dualcore AMD 4600+ runs quite smooth on LOMAC FC. But for this game I think that RAM and GRAPHICS CARD comes into a slightly larger role.

[Prophet]

Proven otherwise. CPU is the #1 factor.

[OldFrankHog]

What about quad core ? im thinking of buying a qx6700 ?

[Prophet]

Since LOMAC only uses 1 CPU, it wouldnt see any difference. Though for other Windows tasks?

[OldFrankHog]

I understand that but wouldnt all the other aplications be shared on other cores leaving 1 core dedicated to Lomac hence making it run smoother ?

 

Coz the quad core is pretty much the same price as a dual core x6800 so I figured might aswell get the quad..from the reviews I read it performs a lot better for multi-tasking applications. For example playing mmorpg's on 2 clients with comms...

[Andrew_McP]

I moved to dual core purely because I was told Fraps would run better on one core, with LOMAC running on the other. However I was completely underwhelmed by the dual core experience and see so real evidence that LOMAC is smoother for having a core all to itself. The various background stuff is called background for a reason... there's not a lot of CPU cycles involved. :-)

Don't forget to set CPU affinity if you're running two "singles" applications concurrently with each other.

 

Other wise, they'll both be doing "core sharing" rather than utilizing a dedicated core.

 

I have several dual core systems (Intel and AMD) and they both perform perfectly fine. Though in clock comparing a single core 3800+ to it's X2 brother with all other hardware the same (on a socket 939 motherboard), there are no appreciable differences in the performance.

 

On the dual core, though, I can set the processor affinity for LOMAC to the first core and fraps to the second core, and each maintain themselves a LOT better than trying to run both of them on a single core machine.

Interesting. I've been unable to tell any real difference when I forget to set the affinity for each process. I must try again some time and be more scientific about my tests.

I was going to get the top dual core Core2 but after watching the Quad core prices range similar prices I decided to skip dual core altogether and start saving for a Quad. There is already at least one game Im about to buy that uses quad processing.
