Hi Bob,Just to let you know I have at last solved my graphics tearing problem when running FSX Acceleration. As you suggested, I forced Vsync ON using the Nvidia Control Panel and thankfully this did the job. I did try using nHancer first but for reasons I'm still trying to find out, that didn't work. I assume that would have done the same thing.Hopes this helps others with graphic tearing problems using FSX Acceleration.Peter

Thanks Bob, understand now, so I will reinstall FSX Acceleration, uncheck the DX10 box and then set up and configure nHancer as per Nick N's guide.I think Nick's guide also said that nHancer will need to be set up each time you update the graghics card driver. so I should become very conversant with nHancer !! Regards,Peter

Thanks very much 'sargeski' for your reply. Great to know I should be able to solve my tearing problem. Could I just check that when you say "However, if you run FSX in DX9 mode you can force Vsync on either in the Nvidia Control Panel or by using nHancer", you mean using FSX Acceleration in DX9 mode by unchecking the DX10 box, and then using nHancer ?Nick's nHancer guide looks a bit daunting, but if thats the way forward then so be it !! Just a thought, but when I revert back to FSX SP1, which I assume uses DX9, (where I don't get the tearing) why don't I need to use nHancer to force vsync on then ?? Sorry about more questions but I just need to understand fully why SP1 is OK and SP1 + SP2 is not OK.Thanks Peter

Hi All.I'm new to this forum but hope I can find some answers/suggestions to my 'tearing' problem. Running FSX SP1 on my Vista 32bit PC with an Nvidia 8800GTX 768Mb graphics card, I have no problems at all with graphics. (I update to the latest drivers for this card from the Nvidia site as soon as they are released).As soon as I install FSX Acceleration (which includes SP2) the graphics become unstable with quite bad horizontal tearing when panning (I normally use Track IR in the 3D cockpit, but the tearing also shows if I use the joystick hat switch to pan.If I uninstall FSX Acceleration(SP2) and revert back to FSX SP1, all is well again with no graphics tearing problems.I can

Hi all As per the post above from 'dbrucem', I have some Vox ATCx voice pronunciation problems I would like to modify in the speech engine mentioned above. The post said "There is a dictionary located in the ATT data folder". I think I have found the dictionary file 'en_us.dict' but I cannot open the file with a .dict extention. Can anyone tell me if this is the correct dictionary file and if not how to find and open it please.Thanks Peter

Hi all I have Windows Vista on a new PC with FSX and have Vox ATC uk for FSX installed and operating OK. I have recently installed FS2004 on the same Vista PC, but after installing the original Vox ATC Deluxe for FS2004, I find it will not operate correctly. It has installed ok but will not get past the 'Initialze' stage. Is there a Vista update for Vox ATC Deluxe please ? ( I am assuming it is a Vista / Vox ATC Deluxe problem at this point ) Thanks Peter Bailey

HiThanks for the nhancer suggestion. I had tried changing the globlal vsync setting in the Nvidia Control Panel to "force on" as suggested by Bert in another reply but unfortunately this did not stop the horizontal tearing effect when panning.I have now downloaded and installed nhancer to give this a try. Did you select the Vertical Sync 'on' option in the global settings or use the MS Flight Simulator X Profile in some way ? I am still using the 163.75 driver in the 8800GTX as 169.25 was not as crisp using photoscenery. Which driver were you using when the tearing problem was solved? Any further tips on how you used nhancer would be appreciated.Thanks Peter

Thanks for the additional info that I can try on my system - I hope to get a reply from Bert about what settings he changed in FSX to get the SP2 vsynch default setting from 'off' to 'on'. Did you change your SP2 default vsynch setting as well ?Thanks, Peter

Bert,Thanks for the suggestion, sounds well worth a try, especially if SP1 defaults to vsync=on ? In my Nvidia graphics card control panel the vsynch is set to "as required by application" so I assume the SP2 default would turn it off. Could you just explain which setting/s you changed to over- ride the SP2 default please.Thanks.Peter

Jim,Thanks for the comprehensive the reply. I will use your setup info as a start point and tweak from there. Having tweaked FSX+SP1 to be very stable on my system with crisp and clear textures, running at an average of 30 fps, I'm a bit reluctant to start again, but I suppose this seems to be the name of the game in our flight sim world !?!?!Regards, Peter

Thanks for the reply Jim. I have 2Gb of ram and the 8800GTX card is the 768Mb version. I have no graphics problems when reverting to FSX + SP1. Did your graphic problems start after installing the Acceleration Pack? I'll give your suggestion of turning down the display sliders a try - did you turn down any particular display slider/s or just 'play' with them all? Thanks and regards,Peter

I have just installed the FSX Acceleration Pack and I am now having graphics problems that I do not have running FSX + SP1. The main problem is most notable when panning ( using Track IR or Hatswitch) in the 3D cockpit view. There are horizontal jagged type lines across the centre of the screen both on the cockpit window frames and also on the distant scenery. If I uninstall the Acceleration Pack, I have no graphic problems and all panning views are very stable. I'm using Vista and Nvidia 8800 GTX graphics card. Anyone out there with similar problems or any ideas please ??

Paul - I have now set Affinity for VoxATC UK to use only the second core as you explained and I'm very pleased to report this has all but solved the stutters. I just get the occasional blip now, with most flights completing without any stutters at all. I found that in "Task Manager" VoxATC when enabled, for some reason does not appear in the "Applications" tab, but does under "Process" tab. Above the "Select Affinity" option was another option for setting "Priority" and I noted this was set to 'High'. As you probably know, I have to reset the VoxATC Affinity setting to use core two only every time it is enabled, a small price to pay for enjoyable simming again.Thanks for your help Paul - Peter

Thanks for your reply and suggestions Paul. I see you use XP as your OS. I know other simmers who have similar PC specs to me, but still use XP instead of Vista. They also use VoxATC UK, with no stutters!! If I increase my fps to unlimited, I think there is a slight improvement in VoxATC stutters but they are sill quite noticable. If I set fps limit beyond 30 I start to suffer progressive photo scenery loading problems, so 30fps limit seems to be mysystems 'sweet spot' where every thing else (other than Vox ATC !) runs very smoothly. Perhaps I need to spend some time tweaking all those sliders (AGAIN!) to find another acceptable setup. How FSX and addon programs decide to use my Intel core2 Duo is way beyond me, but I assumed they shared across the two cores ?? or may be just use one and over flow to the other - help!! However, from what you say, I assume that an 'affinity setting' can control which core a program runs on. So Paul, if your suggestion of changing my VoxATC program to use the 2nd core could help/stop the stutters, I'm more than willing to give it a go, assuming it's not beyond my limitations! So, can anyone out there please point me in the 'Affinity' direction, or better still, has successfully played with their own 'Affinity settings'!?! Thanks, Peter

I have a fairly high spec PC with Intel Duo2 core 6600 2.4Ghz, 2Gb ram, Nvidia Ge-force 88oo gtx 768mb graghics using Windows Vista Home premium 32bit. The only two additions so far are Horizons Gen X photo scenery and Track IR. Since the SP1 update, FSX has run very smoothly at 30 fps. My new addon is VoxATC UK DVD version that includes the new voices.When VoxATC UK enabled, normal flying is still very smooth at 30fps, but when I communicate with VoxATC, their voice replies and text changes in the Prompt window causes bad sim stopping stutters. Any ideas or similar problems out there please from other Vista users ?? Peter
