Sadly I need to tell you to not to use NHancer as that is a big cause of frame rate deterioration in Vista 64 bit and Windows 7 64 bit. I think there will be an update coming which will fix the problems but for now I would use FSX without it. Just activate Antialiasing and Anisotropic in the game and use a higher resolution. Things will be better. NHancer will be back, but major changes are needed.

I'm very interested in this accusation about NHancer causing frame ratedeterioration in Windows 7 64 bit? I'm buying a new computer that hasW7.Please provide as much information as you can as to validate whyyou feel this way about NHancer.Is this your own opinion?Did you hear/read it somewhere? Where?Thank YouJB

Uhhhh, no.I run nHancer with Vista x64 no issues....

I completely agree with ryanbatcund on this -- I've used nHancer with both the Win7 RC1 and Vista64 with no issues; furthermore, I wouldn't fly without it and NickN's settings for it...makes a world of difference for the better on my rig.

Ditto on Nhancer. I'm using it on Windows 7. I've done plenty of comparisons between Nhancer and the default FSX AA/AF, and running with pretty aggressive AA settings via Nhancer doesn't seem to cost me performance or stability. It also allows me to override the FSX AA parameters to ensure I can AA things like trees. Looks much smoother.For the original poster...The first thing to test is what sort of "ceiling" you've hit on performance. Is it your CPU or your GPU? Typically, FSX is CPU-bound, but at high resolutions it's certainly possible that you're outpacing the capabilities of your card. Try (temporarily) lowering the resolution and AA--does this generate a significant jump in performance? If not, you know you need to focus on increasing the bandwidth available to your CPU. In my experience, this comes down to your aircraft, traffic and autogen. Unfortunately, you're flying complex heavies and probably want a realistic traffic environment, sou might first try fiddling with autogen and keeping UT2 traffic dialed in a bit conservatively. You might consider trying the autogen tweaks (TERRAIN_MAX_AUTOGEN_TREES_PER_CELL and TERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL). On my system, these tweaks work great for Orbx FTX flying ... less so elsewhere in the world. Also, zero out the cars and boats or set them under 10%; this will help a lot around metro areas.If indeed you're stressing your GPU, try some more conservative anti-aliasing settings. Nick's are pretty aggressive for higher resolutions. Also, for the heck of it, see if dialing down the water makes any difference. In a heavy, you're probably much more focused on the airport environment, the cockpit, and traffic than the scenery. Sacrifice what you can "out the window".Finally, I would suggest that you want to be a bit methodical about tweaking. It's too hard to go by "impressions". Set up a repeatable autopilot flight, and get fraps or the benchmark utility here in the library. Start with all traffic off, dial-in your performance, then start adding traffic and see what your system can bear.Good luck.

Windows 7 and Enhancer work absolutely great for me. Unlimited set and most sliders to the right. Water at mid settings, and I often get frames in the 50s and 60s. In New York, I may be in the 25+ area but no stutters. Love it.Stan

Ditto for me Stan-isn't it great! :(

TExture Res @ 1mWater 1x high or 2x lowScenery Complexity @ Very DenseAutoGen @ DenseWeather @ 60 mile draw distanceAI in FSX @ 0 for both Airport Ground Vehicles @ minimumBoats @ whatever floats your boat I have mine at 20% for bothHere is the big KICKER for me..... Turn off ALL GA in UT2 and deslect it to make it not visable. This allowed me to run MUCH higher Commercial AI. This is assuming you want to fly bigger jets. If you taste is VFR flying then do the reverse and turn off commercial and turn on GA.I also run with Combined 4xs aa in nHancer. I can run 8xs but see a big hit in weather with that. 4xs allows me to run Real World Weather better.

I have a similar rig and addons to you.Firstly - Get rid of all moving road traffic. It's not necessary. You'll get 10fps right there.Next, drop Autogen to Dense and Scenery Complexity one notch.Frame rates to Unlimited and let NHancer run your card.You can achieve smooth 25+ at Heathrow and Kennedy with complex jets. I have zero issues. FSX runs better than FS9 ever did.

It does indeed depend on what eye candy you are willing to sacrifice...I agree on the road traffic, set it to zero.Trees can be bad too, so keep Autogen under control. Also get rid of all the door exits on your AI aircraft so they will not trigger any jetways.Lastly, I get good results by using the framerate limiter application, and have it set to 30,with FS set to unlimited. Very last topic is weather... fly in fair weather as much as possible, if you want best performance. :(

I am sorry Lee, but that sure isn't my experience with Nhancer. I had it set up as per Nick's settings and use the FPS utility as advised, resulting in much better and smoother FPS than I have otherwise. In both Vista 64 before and Windows 7 now, it is the difference between "not bad" and "very good." If there is going to be an even better version of Nhancer coming that will be even more beneficial, that is great, but I sure do not understand where your negative opinion is coming from. :( No criticism implied, for everyone is entitled to an opinion, but I am curious as to why you believe that. To the original poster, the use of Nhancer and FPS is still the best combination for superior performance, along with being conservative with your autogen. I slid mine back a single notch for added smoothness.Try to keep the blue side above the green.Stephen :(

Hi, I made a video guide that helps explain what the sliders in FSX control and how they effect performance:http://www.youtube.com/watch?v=hepdQ2j6iPYThis is not a "How to Get Maximum FPS" guide. This might help not just the OP, but others who want to learn how FSX really works and what thosesliders really do?ProFlightSimMedia

Just thought I would update everybody....I tired countless variations of autogen, view distance, traffic, etc.. to no avail....THEN, I did the one thing I have yet to try (yes it will probably be obvious to some folks out there)...........I turned off "Aircraft Casts Shadows on The Ground" (or something to that effect...NOT the self-shadowig option). WOW......HUGE difference. I can honestly say my performance increased at LEAST 50%-75%. Still, almost full right settings (water at Med 2x, GA traffic at 50%, road traffic off), almost 100% AI at FSDT KLAS and I am getting about 25 fps in the PMDG J41. Strangley enough, it is perfectly smooth...which seems wierd. I expected 25 fps to suck.Almost full right settings2560x16008xFSAA and 16xAFAlmost 100% Airline traffic at FSDT KLASPMDG J41All smooth. WOW. It's like a new sim. I can only imagine what I could get if I was a little more conservative with my settings and not such a graphics **. Ironic considering I just responded to a post today stating I use shadows because the sim doesn't looks right without them. Thanks for the help everybody!!!Got a J41 to catch. :(

Spoke to soon....... Restarted the sim and my performance was back where it was before. Looks like I might just have to drop off the AI a ways.

I can confirm no detrimental effect from nHancer at all. W7 64-bit, set up as Nick's instructions, no issues great frame rate and minimal shimmer.No idea where the notion that 'nHancer is detrimental' came from but I see the original poster hasn't clarified that statementmartin.

I thought that n-Hancer was just to increase quality?? To me that could result in a frame hit.jja
