Run the game's built-in benchmark before and after each change. Start by lowering the overall graphics preset, then reduce shadows and other detail settings, keep video-memory use within the available amount, and disable mods while testing. Update the graphics driver and make sure the game is installed on an SSD if battles still stutter.
Open Options, choose Graphics, and run the Battle or Campaign benchmark that best matches where you notice the problem. Write down the average FPS and watch for sharp pauses. Use the same benchmark after every change so the comparison is fair.
2
Start with a lower graphics preset
Move the overall quality preset down one level, apply it, and run the benchmark again. If the result becomes much smoother, keep that preset as a safe starting point and raise individual settings later.
3
Lower shadows and detail first
Open Advanced Graphics and reduce Shadow Detail, Unit Detail, Effects Detail, and other detail settings one at a time. Large battles draw many units and effects, so these changes are usually more useful than changing several unrelated options together.
4
Watch the video-memory estimate
Keep the estimated video-memory use below the amount available on the graphics card. If it is too high, lower texture quality or resolution scale. Avoid unlimited video memory unless SEGA support specifically asks you to test it, because it can move the problem into slower system memory.
5
Disable mods for one clean test
Turn off all mods in the Total War launcher, restart the game, and rerun the same benchmark. If the stutter disappears, enable the mods in small groups until the conflicting or outdated one is identified.
6
Update the driver and close heavy apps
Install the current recommended graphics driver, restart Windows, and close recording, browser, and other memory-heavy programs you do not need. Compare the benchmark again before changing more game settings.
Warhammer III should run from an SSD with enough free space. If pauses happen while loading the campaign or battle assets, confirm the install location. If performance falls after longer sessions, check temperatures and cooling before assuming the graphics preset is the only cause.

If it does not work
If only one campaign save performs badly, compare it with a new unmodded campaign before reinstalling the game. A large late-game campaign can be more demanding than the benchmark.
If the benchmark is smooth but campaign turns or menus pause, check SSD space, mods, and background storage activity rather than lowering image quality again.
If the game crashes after a driver update, perform a clean test with mods disabled and consult SEGA's current Warhammer III support section before trying unsupported launch commands.
