Bueno, puede ser que haya otros procesos o aplicaciones que estén haciendo uso de la CPU y la memoria al mismo tiempo que utilizas el simulador, lo que restaría bastante rendimiento al PC.
En el Administrador de tareas puedes ver que procesos se están ejecutando en tu PC.
A veces virus o malware pueden estar haciendo uso de toda la capacidad del ordenador.

Boosher,

I realize that you're using MS Security Essentials but, as with all A/V software, it won't catch all.
Just to start with the obvious causes do the following:

1. Check processes for Indexing Service. If it's running, disable it.

2. Un-install MS Security Essentials.

3. Install, if you don't already have it, CCleaner. http://www.piriform.com/ccleaner

4. Install, and update, Spyware Blaster (This is your systems condom). http://www.majorgeeks.com/downloadget.ph...f4682b4cef
- After updating, apply all new immunizations.

5. Install, update and run, Spybot Search And Destroy (This is phase 1 of your systems Penicillin Shot). http://www.spybotupdates.com/files/spybotsd162.exe
- After immunizing and scanning your system, remove any Spyware, Mal-ware, hostage-ware etc that is found.

6. Install, update and run, Malware Bytes Anti-Malware. (This is phase 2 of your systems Penicillin Shot). http://majorgeeks.com/downloadget.php?id...666f809b26
- After immunizing and scanning your system, remove any Spyware, Mal-ware, hostage-ware etc that is found.

7. Run CCleaner to remove any un-needed registry entries.

8. If you're running multiple H/D's, run the game from one of the alternate drives (D, E, F etc.)

9. Disable swap file, system restore on any drive other than your Windows Drive.

10. Swap file should only be enable on the primary H/D (Windows) and should be double your ram size. ie. If you have 4 gb of ram, swap file should be 8gb.
- Reboot the system.

**** Most import step ****
11. Download and install Disktrix Ultimate Defrag. http://www.disktrix.com/downloads/Ultima...pTrial.exe
- It's a free 14 day trial, but is well worth the trouble.
- Run the software and move all Windows Files, Boot files to the outside sectors of the drive and the swap file to the End of the drive. This will help alleviate a lot of read/write seek times.

This should help with anything that may be lurking in the background of your system hogging up resources.
If this isn't enough of an improvement, we'll start with the next step of looking at your setup for IL2, Video and hardware pipelines. (Updates to MB BIOS, Video BIOS, Video Drivers etc.)

S!
