Hi,maybe this is a dumb question, but I'm thinking about replacing Pentium IV 3.6 GHz CPU with a faster one. This will then be a dual-core type or quad-core-type. (I know...... I will have to replace the motherboard as well)As I understand not all programmes (software) will be affected by such a change as they aren't programmed to que up tasks with multi-core-technology.What about FS9 ? If I replace the single 3.6 GHz CPU with lets say a Core 2 duo 3.33 GHz - which should result in about 6 GHz processor speed; will I get a FS9 performance in accordance with this upgrade ?Carl

This should be in the hardware forum but anyway.... A core 2 Duo 3.33 Ghz will not give you 6 Ghz in FS9 or any software. However these Core 2 chips and the I7 Chips are much more efficient then the old Pentium chips. Even with a Core 2 running at 2.4ghz you will see a huge boost over the old P4 running at 3.6 ghz. Rob

When I replaced my 2.4 P4, 256mb AGP, with a 2ghz, C2 Duo, 256mb pcie. ... Huge difference.Bob

even though Fs9 is not a multithreaded application software, it will run faster with a quad core than a dual core. its not just about speed of the CPUs but the other tech in it too. which is why y9ou will see a 2.5ghz quad ###### all over a 4ghz dual core. one core for the game. other cores for the background thingsthat run in windows. get the quad.

What about FSX?Lot of rumors I've been reading that FSX needs a high clock speed, and a dual core 3.0 Ghz is better than a new i7 quad core at say, 2.3?

Yes clock speed is very important, but there are so many other factors involved. In your case I would say buy the i7 get a good cooling system and overclock it. Raiky, your comments could be misleading to users here that don't fully understand how these processors work.In certain cases (for example mine running applications on multiple machines) the Dual core would be a better option.RegardsRob

I would not be so quick to state this. This is esp true for fs9. From all the research I've seen, and a bit of common sense, I beleive you're better of getting a faster lastest generation core duo then a quad. ps....2.5 quad 'pissing' all over a 4ghz dual...you must be kidding...

Never ever, especially not in FS9. That would be the day when quad 2,5 beats core2duo 4,0 in FS9. I have [email protected], and trust me, no quad at 2,5 can beat it. OC quad to 4,0, sure, beats the c*ap out of it, but other than that...

Many misleading things on the "Internet".

FS9 runs in a single thread and cannot make use of multiple physical CPUs (multi core) or virtual CPUs (hyperthreading). But it can, and does, benefit greatly from the technological improvements that come along with the dual/quad core CPUs.But that said, it's not as simple an issue as number of cores, or of clock speed either.A Conroe or Penryn Core2Duo at the same clock speed as your pentium 4 will massively outperform it because of the improved design of the CPU, which allows multiple instructions to be pipelined simultaneously.FS9 running on some of the newer quads can marginally outperform the dual-core CPUs at a given clock speed because they have larger high-speed memory caches.And the Core i7 quads perform even better due to their large caches, relocation of the memory controller to the CPU chip, triple vs dual channel RAM, and other architectural improvements.But given that FS9 runs in a single thread, clock speed does matter. A highly overclocked dual core Penryn running at over 4 GHz can indeed run FS9 faster than any quad running at a stock 2.66 GHz clock freq. But it won't beat an overclocked 4.5GHz Core i7 with fast triple-channel RAM pushing triangles over a fast PCIe bus to a fast GTX285 with 1GB of fast VRAM.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Bob,Recently I read a tip in PC Pilot magazine, aiming at FSX. I tried to apply it for FS9 and I can get both processors working for FS9 at the same time.Add the following to your FS9.cfg file (make a backup copy first) :[JOBSCHEDULER]AffinityMask=3With FS9 running, in Windows taskmanager, processes tab, right click on FS9.exe and click assign affinity (bottom line). You will see both processors checked, but only CPU0 is actually being used as you will see in the performance tab. Now, unclick CPU0. This effectively assigns all CPU1 power to FS and this could already improve your performance. Now, click CPU0 again (check on) and FS9 is effectively being run using BOTH processors. Check the performance tab.Try it, it works for me :(Best regards,Eric

I have to disappoint you, this trick actually costs you performance.FS9 runs on one core at a time. You only allow usage of more cores, and the difference between this scenario and staying on one core all the time is that you loose performance on core switching.

Correct. For FS9: the best CPU you can afford (if you can't afford i7, then get a fast quad or last generation C2D, the E8600), OC it the best you can, reach 4.0ghz+ and you are in heaven. Simple as that (considering CPU ONLY). And do run it on the first core.

I know this has been talked about to death but you folks in here seem very knowledgable..so I'll run this by you guys once, and a simple no or yes answer will be plenty.Is there any true benefit to unchecking 1 of the cores on my dual core when running fs9?
