The PC version of Modern Warfare 2 has received another patch which, among others, brings improved placement detection for sentry guns, sprint speed balancing as well as mouse latency tweaks. The changes listed below are said to be the “major” ones, so there may be others as well. As usual, Steam will apply the changes automatically the next time the client is restarted.
# Care Package, Emergency Airdrop, and Sentry Gun marker grenades sprint speed normalized
# Sentry Guns: Improved placement detection, preventing cases of Sentry Guns inside geometry
# Model 1887: Bling using Akimbo and FMJ combination now has same range and damage as non-Bling Model 1887s
# Improved player collision removing cases of getting into geometry and ‘elevators’
# Mouse latency tweaks for more mouse movement consistency
# Fixes to prevent various texture and XP hacks
