Hello everyone,I am new to FSX...but my system has very low specs, although I have good performance with FS9. My goal is to have a light FSX and to focus on airplane (ie future PMDG NGX) rather than on graphism or scenery.Here are my specs:Notebook Dell Inspiron 1520 Intel Centrino Core 2 Duo 2ghz T7300 RAM 2GO Nvidia 8600m gt 256I read a lot about tweaks in FSX but I am afraid they are aimed at high end specs hardware such as I7, etc. So, I really do not know which one I should be able to try on my computer.I found some resized textures in the library but I read some comments saying it is not a good thing to use such textures...I know that recently, some very important tweaks were found by ******* Altuve but is it aimed at a system like mine?Thank you for your help!Best regards,Pierre

The bp=0 tweak will give you a slight boost, try it. You can always delete your cfg file and start over.

I've been running a dinosaur system close to yours from the begining. Athalon XP2400+ NV 7600GS 512 and 2GB PC3200 on WINXP SP3. I have autogen turned off just because I don't like it. The airport traffic is a heavy hitter so that is at minimal. Keep your sliders down. Better to have a lower resolution that looks pretty decent compared to FS9 and performs well then try to crank stuff up which will cause many a blurries and bog your system down. My frame rates are on the low side, maybe around 12 to 15 except of course around the northeast corridor. Personally I dont pay attention to frame rates, I have stuff running pretty smooth here which is the bottom line. Tweaks from ******* have also worked wonders here. Level-D actually flies pretty well here also. I'm sure when I finally get around to build a new box here I will be quite happy with the better performance and higher setting capabilities.

Thank you for yours answers!Does it mean that I should use less than Very high on global texture setting?Pierre

Keep the texture setting, but turn off autogen and traffic.Start with clear weather (try different settings.. but clouds do hurt performance). Also set the LOD radius to medium instead of high.On your system, it is not so much tuning (forget all the tuning hints)but choosing a lower set of settings which still allow you to enjoy the sim.

My Global Texture Res is set on max. Takes along time to get the right balance of settings on an old system. And then as soon as everything seems good the temptation is there to start cranking things up again so Its kind of a never ending battle.

As others have said but also turn off all object and terrain shadows as well as aircraft shadows, turn down terrain detail to less than 80% and move any cloud draw distance settings to minimum.

Not necessarily since a low end graphics card will choke on too much data being thrown at it - andit must manage it straight away. So careful with this setting for a low end system. water - keep this minimumautogen low/offblume offshadows offweather - clear traffic offThe put scenery and aricraft quality near minimums - turn off all AA and AF (to start with). Nowincrease the things you want to use (scenery quality/aircraft quality) until you get sensible fpswith a mix of flying. Now save.Now turn on AA and AF slowly on graphcis - until fps starts to drop - now you are GPU limiting, soset back AA/AF one notch and you should have balanced the GPU and CPU limits.You may have to compromise with different flying. Use traffic when you want to use this at airportsbut then turn off all water, weather,autogenWhen you are away from airports, or just want to fly without traffic, then you can increase weather/autogen to higher values.
