First let Modern Warfare II finish shader preloading on the main menu. Then turn on the in-game FPS counter, test the same scene, and lower one graphics setting or set a frame-rate limit. Keep only changes that make the frame rate steadier; there is no single boost preset that works on every PC.
Start Modern Warfare II and remain on the main menu while shader preloading completes. Activision warns that leaving the main menu before it finishes can cause performance problems. Begin the test only when the progress indicator is gone.

Record a repeatable baseline
Open Settings > Interface > Telemetry and enable the FPS counter. If Frame Time is also available, enable it; lower and steadier frame time means frames are arriving more evenly. Load the same private match, training area, or short route for every test.
3
Set a stable frame-rate limit
Open Settings > Graphics > Display and set the gameplay frame-rate limit to a value the PC can hold in the test scene. A stable limit below an erratic peak usually feels smoother. Retest the same scene and keep the limit only if stutters or frame-time spikes decrease.
4
Lower the active bottleneck one setting at a time
In Settings > Graphics > Quality, lower resolution scaling, shadows, reflections, volumetric quality, or texture resolution one level at a time. Retest after each change. Keep only changes that improve the measured result without making the image unacceptable; do not copy a fixed VRAM or scaling percentage from another PC.
5
Remove supported PC-side causes
Close overlays, capture tools, hardware-monitoring utilities, and other nonessential background apps for one comparison run. In Battle.net choose the cog beside Play > Scan and Repair, or in Steam open Properties > Installed Files > Verify integrity of game files. Relaunch after the repair completes.
6
Verify the improvement
Run the same test twice. The change is useful only if the chosen frame-rate cap is held more consistently, frame-time spikes are reduced, and the game remains visually usable. Save the settings and stop changing controls once that repeatable result is reached.
If it does not work
If FPS drops after every game or driver update, return to the main menu and let shader preloading complete before judging performance.
If the graphics menu reports excessive VRAM use, lower texture or cache-related quality rather than changing process priority or forcing an undocumented launch argument.
If Modern Warfare II runs more smoothly after background apps are closed, reopen them one at a time. Activision specifically identifies some overlay and hardware-monitoring tools as possible conflicts.
If Modern Warfare II is still slow at the lowest reasonable settings and the PC is below Activision's current requirements, another graphics change cannot remove the hardware limit.
