Hello everyone,I want to start by saying I'm fairly new to the AVSIM forums, but I'm a user from a long time, and I want to say it's an amazing community.I've encountered a problem in my FS2004. I've been playing it for more than 10 months now, after playing FSX for more than an year and I've never had any problems with it... until now. A few days ago my game started slowing down a lot. Mostly in the main menu, where you chose the plane, make your flight plan etc. It takes more than 10-15 seconds after clicking a button. It's seriously annoying, and I've noted a serious frame-rate drop in the game itself.I've been running FS2004 on the highest settings possible, and I haven't had any problems with it, until this one occured. I tried defragging with CCleaner, I tried running it on windowed mode, but nothing helped. I don't want to re-install it, because my game is 40gb with all the addons, and it will take ages to restore them back in the simulator, plus I read that even re-installing doesn't help. I didn't manage to find a good answer anywhere, and I thought my best option is to ask you guys. I'm sure there will be few of you who will be able to help me out.if it helps I'm going to post my computer specs bellow, because I don't know whether that will come in handy or not.I'm running on:Windows XP, Service Pack 3RAM: 2GBCPU: Intel Pentium, Dual, each 2,20 GHzVideo: NVidia GeForce 8500 GT, 1GB Memory.I really need your help, and it will be really appreciated if someone helps meThank you in advance,Regards!

Steve,One thing caught my eye. I tried defragging with CCleanerCCleaner is not a disk defragger. It gets rid of temporary files. If you've never defragged your HD that could be the reason for the sluggish performance especially if it's been getting slowly worse. Try defragging with the standard XP defragger. It's not briliant but it's better than doing nothing.Others may have other suggestions but that's where I'd start.

Hello,Slow down ...Just as precautionary measure .. (if not yet performed) .. try a scan with this very good freeware anti malwares:http://www.malwarebytes.orgNo fuss ...Sometime .. nasty files can slowdown your PCMaybe it's not the case for you .. but why take chance ? :( Regards.Gus.

Hello again,Thank you for your replies.I've de-fragged my Hard drive with an actual defragment tool this time. It was serously fragmented. Once I de-fragged it, I started up the simulator again, and still no luck. It was lagging as bad as it was before. At least I de-fragged my hard drive.I'm currently scanning with Malwarebytes, but I doubt the problem is there, because my PC's performance hasn't changed. It's still as fast as it was ever. The only problem which I have is with the simulator. So I any replies, of any kind, of how can I fix my problem will do good.Thank you in advance!Regards

Did you add anything just before the sim started to slow down? New drivers? New airport scenery?The usual advice is to revert to a default aircraft at a default airport and turn off all scenery layers except the defaults. If your performance returns then a scenery layer is responsible. Add one layer at a time until the problem starts. The last activated one is the culprit.It's hard to advise without being in front of your PC. Oly you know what you've recently changed.

Hi,Have you installed any new software recently or around the time you noticed the slowdown? One possibility is that you have something new in services or start up that is running in the background that is a bad resource hog. Taking into account the information you have given so far, this may be something to at least consider. I hope this helps you find the problem.Best regards,Mel
