I am still new to FSX but not to flight simulation but am having difficulty getting nHancer to kick in and get rid of my jaggies and all of that sort of stuff (including AF). I used nHancer successfully with FS9. I am using the very latest drivers on Nvidia website for my 8800 GTS 320. Is there a known driver issues with nHancer and FSX? Are there any other recommendations?Thanks,RH

How about the in-game AA? It seems to work fine. One question though? Does the "in-game" version work through the videocard or the CPU? In FS9, the in-game AA made performance much worse that in nHancer. I always assumed that in FS9, the AA worked at the level of the CPU.RH

Do you have the correct version of nHancer installed?For driver versions over 182, you need 2.5.1. Also, .Net 3.5 is required.

Also be sure to have a look at NickN's FSX Guide over at Simforums:HEREScroll down and you will see a step by step guide. I have personally used it myself and it works very well. NickN is an expert on this stuff...Regards,F.K.

In some situation it's best to force a hardware mode and in other situations it's best not to.. depends on how your CPU and GPU match up, but you should NEVER force a mode that's higher than the in game especially for FS. The advantage of in game AA is that it saves the hardware GPU some serious rendering time by culling the list of what gets AA/AF treatment. All the AA is always done on the GPU in either case.. its not something a CPU can do well anymore but similar methods to AA are still common for 2D rendering.

Thanks guys for the information. I will check to make sure I have the correct version of nHancer. I am in the process of changing out my videocard from an 8800 GTS 320 to a 9800 GTX+ with 512. Hopefully, the 9800 GTX+ will allow me to see better framerates in AA and AF than was possible using the 8800 GTS. What do you guys think?Thanks,RH

Thanks guys! I got nHancer to work. Upgrading to a 9800GTX+ 512 from an 8800GTS 320 had almost no effect (1 or 2 FPS at the most). Looks like I am going to take the 9800GTX+ back and invest in an Intel i7 machine.

No game does AA via the CPU - it's completely a GPU function. What's happening when you use the in-game checkbox is FSX (via the Direct 3D API) tells the video card what AA mode/setting to do. I've always had MUCH better success leaving this box unchecked and forcing the AA I want via the driver control panel (or a frontend like nHancer), on both ATI and Nvidia cards. I don't like that you have no idea what type of AA is even being applied when using the checkbox. Most game engines that use "application controlled" AA and AF actually allow you to set the level of it, 2X, 4X, 8XS etc, this isn't the case with FSX - you just get "Antialiasing" and "Anisotropic" with absolutely no idea of what those are really telling the card to do.None of today's current video cards will even break a sweat doing high levels of AA in FSX. The GPU is highly underutilized (FSX is a CPU limited engine) and there's a ton of GPU cycles just sitting there with nothing to do - crank up the AA and give it something to do!

But, I see a minimun of 3 to 4 fps improvement without AA than with it, so in the 10 to 15 FPS range 3 to 4, and sometimes more, frames per seconds counts a lot. So, the card must at least be breaking some sort of sweat - that is with my new 9800 GTX+ 512 at least.
