I wish to know if Flight can benefit from a 4core HyperTheaded processor

No it does not.

The official word is that it doesn't. However, run Flight with such a processor while running monitoring software for the CPU. Notice that all threads show high activity, and all cores have a similarly elevated temperature. I might give them the benefit of the doubt that the activity could be wrong, but I'm not willing to say the temperatures are wrong as well.

 

Let the flaming begin.

I have notice the same cpu activity on my 4 core 8 tread.

When look at cpu and temp thay often go all fluxtuating

Also I can see core 0 (from 0 to 7) a bit higher than others.

 

BTW I am using a laptop on i7-2630QM 2.0 only with turboboost at 2.6 when all core working.

I set Flight at HIGH all the way (not maximum) and my CPU is often lower than 50%

 

My biggest restriction is my GPU (Mobility Radeon 6570M) pretty fast for a laptop but still running 98% around large airport.

I can mantain 21 FPS in the large airport and 30 to 60 in more generic

I also notice I get smooter FPS by using Vertical Sync ON. Probalbly Flight is saving GPU cycle not trying to over achive 60 FPS

 

Thank you

Back to the OP question......NO it does not.

Prove it. Please.

How does one prove a negative? I have never figured that out...... :t0106:

Note to the Original Poster: Don't take anyone's word for it. Test it yourself and draw your own conclusions.

 

Bob: The proponents of the "does not use hyperthreading" are fairly fanatical about it. The mere mention brings out some nasty attitudes. The fact that your hardware monitors show something completely different does not matter, and probably accounts for the attitudes. With Flight (or FSX) being the only thing running on the system, all threads in all processors still show a lot of activity.

 

Now, I can understand why something in the system might fool the monitor programs about the activity, but the same monitors also show increased heat in all cores. Since this is measures separately and differently, it's almost impossible that the same situation that could fool the activity counters could also fool the temperature sensors. Oh... and it's not just one monitor program that shows this.

 

While the actual application may not be coded specifically to use hyperthreading, the operating system or bios seems to be handing the job very well. But even then, I'm wondering how they explain the Processor Affinity parameter in the FSX config file.

 

It may be that all 4 cores are used, but all 8 threads are not, and what's showing is mostly the core use, which would also drive up the core temps. But no one ever mentions this. There is always a flat denial that hyperthreading exists.

 

I don't have any idea how this idea got started.

Are we talking hyper-threading or multi-threading? Hyperthreading is an Intel marketing term used for turning 1 physical core into 2 virtual cores and can only be used on some Intel CPU's. Mult-threading is a term for allowing a program to spread itself over multiple cores that can be used on both AMD and Intel CPU's.

 

After doing some quick testing, YES, Flight supports multi-core and quad core CPU's. Not 100% nativly, but its clear that Flight will use extra cores to process things. What its doing, im not fully sure, but without Flight running, all 6 of my cores are flatlines. With Flight running, Core 1 is 100%, and 2-6 are around 10-50% used. So its clear that Flight is using more then 1 core. Here is the proof.

 

Specifically hyper-threading. The impetus for the topic is to decide if a 4core HT chip that will show 8cores to programs would increase performance for Flight. It appears not, which would be consistent with the legacy from FSX.

No U. S. Senator is a Muslim. There are no T-Rexs on the moon. So, yes, you can prove a negative:)

Hyper-threading really is just a marketing gimmick made up by Intel that uses slack CPU time as a new CPU. I havent seen any video game benefit directly from it, so saying Flight shows its legacy from FSX due to that is a false statement in every possible way.

I appreciate that clarification, I just remembered reading in hardware guides on this forum that fsx does not use HT and it should be turned off if possible in the bios.

I heard the same thing in FSX, but that does not apply for Flight. It may not directly use HT, but HT wont hurt Flight since it was built using computers with HT ;)
