Hi *******,First, Thanks for the tweaking tool - it certainly helped improve smoothness and gave me a good base from which to ask more questions - and here they are!:First, machine specs:Dell XPS M1730 laptop / Core2 Extreme x9000 OC'd to 3.8Ghz / dual Nvidia 9800M GTX SLI / 4gb RAM / Win7 Ult x641. It's fairly clear my CPU is bottlenecking performance, even at 3.8Ghz, so how can I load-up the GPU more for better balance? I realise FSX is optimised more for quad-core processors, but I'm stuck with my setup and for a laptop, it's pretty good on other games.2. Can you give me some hints for SLI settings in Nvidia Inspector, please, or are the default FSX settings OK?3. I am having trouble setting-up FPS Limiter 0.2; double-clicking on the JAR file just opens my Nokia OVI phone sync. app!! I made sure I have both 32-bit and 64-bit JRE versions, but I'm stumped with this one. Any ideas, please?4. In the absence of FPS_Limiter 0.2 I am using Antilag with success but not really sure about the RenderAheadLimit setting of 1 or 2 (or 0 to disable) with my hardware setup. Also, you advise setting FPS limit to *exactly* 20; presumably if there's good smoothness at 20 I can raise the limit a few at a time without other penalties? Sorry to ask about stuff you didn't write but I figured you might be able to help. Again, thanks for your tweak tool; as a FSX newbie it is a great help!Cheers, Andy
