Fixing CA and Reducing The Lag
Please follow these steps, they helped me to be able to play Combat Arms after the new patch. I've tried reinstalling the full game client, manually updating hackshield, running as administrator, and changing the compatibility, but to no luck. This method however worked perfectly for me, thanks to my friend who helped me out because he was having similar problems.
Steps:
> Right Click Combat Arms icon
> Properties
> Compatibility
> Uncheck/Disable Compatibility Mode > Check/Enable Disable visual themes > Check/Enable Privilege Level
> Apply
> Start Menu
> Control Panel > Classic View (On sidebar) > System > Advanced system settings (On sidebar)
> Advanced tab > Performance > Settings
> Data Execution Prevention Tab > Click Turn on DEP for all programs ans services except those I select
> Add
> Combat Arms Folder > Select both CombatArms and Engine > Open > Apply > Restart your computer
After restarting your computer try and play Combat Arms to see if it worked.
