Hi everyone, first post, great wealth of information here at this site.I have searched here and elsewhere, I can't seem to enable Vsync in FSX, either by adding those lines to the fsx.cfg file, in the Nvidia control panel, or with Nvidia inspector, and I'm wondering if it just won't work with my system, or if there's something I'm overlooking. Here's my setup:FSX Acceleration, X-Pack, latest version as far as I know, Windows 7 Home Premium 64-bit. Nvidia GeForce GTX 570 with the latest 266.58 drivers. The sim is running off a gaming-dedicated SSD, I have 8GB of RAM, and all is processed by a Core i7 870. My monitor is an ASUS 1050p LCD, and I use TrackIR. Performance in FSX is actually very good, but I get horrible tearing moving views around the cockpit, and it's driving me nuts. Is there some antialiasing setting or framerate cap or some other thing like that I should be doing in addition to either modifying the .cfg or forcing Vsync on with the Nvidia control panel or some third-party software?Sorry to bring up this tired topic again, but I'm out of ideas. Thanks!

Should work. I have a fairly similar system (same operating system, card, drivers, SSD). I have VSync enabled through nVidia inspector and using the lines in the FSX.cfg file that Bjote recommends. VSync has not been a problem with any nVidia card I've owned; ATI/AMD cards are another story...Cheers,Noel.

WPAIs there a difference if you pan with the "HAT SWITCH" to when you pan with the spacebar and mouse. I see the same issue as you (with Bjote's auto config) with or without FSP_Limiter when I pan with my joystick or yoke. There is much less effect when I use spacebar + mouse to pan. I have changed my game controller pan speed over the years so that may be giving me this effect with the joystick, so there could be an optimum setting?? Please disregard this post if this doesn't happen on you rig!RegardsPeterH

Thanks for the replies, much appreciated. No luck - I added both lines to the fsx.cfg under "Graphics" and forced vysync on with Nvidia Inspector, both with and without triple buffering. No effect in-game, unfortunately. I also tried changing pre-rendered frames from 3 to 2, 1, and 0, as I recall this needed to be done to force vsync in DCS: Black Shark, but also no effect.The problem is equally bad between TrackIR, hat switch, and keyboard.

Hi,I had the same problem you described, the only fix I've been able to find was by adding the following lines to FSX's config file:[bufferpools]PoolSize=8388608RejectThreshold=98304UsePools=1Not sure if you have this setup already, if not its worth a try. Just add the above text to your fsx.cfg file.

Thanks for the suggestion, I hadn't tried that yet. Alas, didn't work, with or without the "force" commands whatever the Nvidia Inspector setting. What a strange problem...

Perhaps it would be worthwhile pulling your Nvidia drivers out then run drive cleaner and re-install the latest drivers. Have you got these statments in your FSX.CFG file:ForceFullScreenVsync=1ForceWindowedVSync=1

Are you running FSX in windowed mode (vs. full screen mode)? If I recall correctly, vsync only works for windowed mode if a frame rate limit is set that is a power of 2 multiple of your monitor's refresh rate, e.g. FPS values of 15, 30, 60 work for a 60hz monitor. If you can see the standard windows boarder around FSX, you are in windowed mode even it it fills the screen. I hope this helps.

Hmmm, no dice. The lines are there in fsx.cfg, I'm in full-screen mode, clean driver install, I've tried forcing it on with Nvidia Inspector and the Nvidia control panel, I've tried it with the framerate set to my monitor's refresh rate. Arghhh...the sim looks fantastic but that tearing is very distracting. Well, thanks for all the suggestions and advice, very kind of you all.

Interesting - if I disable "Preview DirectX10" the tearing goes away, but performance and image quality drops a lot. Re-enable it, smoothness and beauty is back, along with tearing. I'm not sure if this has anything to do with anything, but I thought I would mention it.
