Classic British Flight Sim

Hey Moderators! Please will you stop Peter from posting pictures of tasty aeroplanes? I kept thinking about that pretty little Cirrus that he showed us the other day and I knew I wouldn't be able to resist it. It was my weekly weighing day today and I've lost another bag of sugar in the last week so I deserved a treat.





It flies very nicely but unfortunately hasn't got nosewheel steering (as per RW) and I don't use pedals. I've programmed a couple of keyboard buttons for differential braking and it works surprisingly well. I've done a couple of basic flights but I can't tackle anything too adventurous until I've read the manual about what all those knobs do. I've got the pdf on my iPad so feet up for an hour or so with a nice cup of redbush tea

I highlighted this a while back. You've only yourself to blame

Hi Ian,

I don't have rudder pedals either but as far as I remember, all I had to do was set the steering angle to 40. I don't remember what it was before but I tried 60 and when that felt a bit fierce I reduced it to 40. Of course this only helps if you have Autorudder ticked.

BTW...On another tack, I did a trial today by setting up a fiercely demanding startup flight at McLeland Field with HT enabled and the AffinityMask at 84. I then started P3D and allowed it to go to the Previous Flight as set up and saved by FSUIPC when I exited. The frame rate averaged 9.3 FPS. I then exited again and restarted windows to get into the SETUP to disable HT. When windows had restarted I set the Affinity mask to the correct setting for HP disabled (14) and started P3D, again allowing it to start in the Previous Flight. The frame rate now averaged 14.2 FPS and that is a big percentage increase. My chip is a Core i7 920 at 2.66 GHz and it does seem to prefer to operate with the HT disabled. Note I was running the EPU6 engine in Auto mode and I don't think it came out of Pedestrian Mode to get those figures so it was really running a bit underclocked. However, both runs were the same demanding situation with the only change being Hyperthreading and AffinityMask.

OK. Thanks for that, Peter. That ties in with what my tuning guide says. HT off, AM=14 and HT on, AM=84. FSX SP2 supports multi-core but not HT so HT should be off. However, Prepar3d does support HT so apparently it should benefit by having it switched on and that's where I am at the moment.

But if you're finding it beneficial to turn it off and just use the cores then I'll give it a try. I'll let you run it for a few days and see what you think and if you feel it's beneficial then I'll try it. I'll try that nosewheel setting as well although using a couple of keys under my left hand seems quite easy to control - it's much smoother than you'd expect.

Thank you

Ian

Peter - I just tried disabling the HT but I get exactly the opposite result to you! Using a saved flight I started it by double clicking directly on the FLT file and with no further input recorded the fps at 30. I exited P3D, rebooted and disabled the hyperthreading and reset the Affinity Mask to 14. Windows and P3D were slower to load and the saved flight ran at 24 fps. Reverting back to HT and AM 84 brought it back to 30 fps again.

My only suggestion is that the Ivy Bridge processor uses the hyperthreading in a different way to yours At least I can sleep properly knowing that I'm running at optimum (possibly ).

I followed your suggestion with the Cirrus and set the steering to 40 and the joystick now controls the ground steering satisfactorily. So thank you for that.

Ian
