Little update: i used Game booster, but i didnt saw any diference. It just killed 2 process anyway.Matias

Typically Gamebooster will disable quite a few processes, a lot more than three. Also it looks as if you registry needs to be cleaned, as there are a lot of entries i am seeing there that no longer exists - just good general maintenance to keep it as clean as possible. It may be a good idea to open up event viewer and carefully read the logs there as well, and see what could be causing this.

I want to ask you guys, if someone experienced something like this or if someone knows if this is a normal behavior.after about 30 seconds or less the 4 cores goes to almost 90% and the FPS drops like 20 or more and its stay there.You may think that 25 FPS y quite nice (and i think that too) but the problem is that after install ActiveSky X and PIC 737 im in 8 FPS and i can't fly like that.

Normal behavior is that FSX will run the lowest core available to it at close to 100% all the time.The remaining core(s) are used for texture loading and can be at 100% while scenery is being loaded.If you hit the P (pause) button, the other cores should after a while, drop to zero.All cores at 100% in heavy scenery is not unusual.Also, 2.5 MHz for the CPU is marginal for FSX.... so 20 fps is to expected also, I am afraid.Do a test at Lihue airport on Kauai.. there is a lot less scenery to load and yet pretty scenery to fly in..

Yeaph Bert, I'm affraid your right about the Mhz. But i remember did a couple of flight in FSX with PIC 737, and with Global 2010 ActiveSky X, UTX, and MyTrafic X, and it was flyable. I don't know why now its acting like this. The only thing i can think of is that now i have installed a newer version of nVidia drivers (the latest).Matias

I like the 257.15 drivers for the visuals, but the 182.50 drivers are the best for performance on older cards (like yours and mine..) :(

Hello AllI'm back to this topic 'cause i just wanted to let you know that im having the mosta happy day of my life.I'm finally able to fly on FSX with 25 smooth FPS.The solution? FPS Limiter. The little program the made the dream real.Thanks all for your answers and i hope that any that come to this topic finding a solution for a problem similar to mine, find the answer here.Happy flyingMatias
