In Dota 2, open Settings > Video and use Advanced Settings. Keep your normal resolution first, lower Effects Quality and Shadow Quality, and reduce Game Screen Render Quality slightly only if more FPS is needed. Close heavy background apps, update the graphics driver, and verify the Steam files. Use Valve's -autoconfig or -safe launch option only when the game will not start, then remove it again.
Load the same demo, bot match, or training area and repeat the same camera movement and spell sequence. Note the current resolution, rendering quality, effects, shadows, and approximate FPS.

Open Advanced Video settings
Open Settings > Video and select the advanced settings view. Take a screenshot or write down the starting values so you can undo a change that makes heroes, particles, or the minimap unclear.
3
Lower effects and shadows first
Move Effects Quality and Shadow Quality down one level, apply, and repeat the same test. These settings affect busy fights, so compare them before lowering every texture and display option.
4
Reduce render quality carefully
Keep the monitor's normal resolution and lower Game Screen Render Quality a little if more performance is needed. Stop when hero outlines, spell effects, terrain edges, or text become difficult to distinguish.
5
Keep a stable display mode
Compare Exclusive Fullscreen with the current borderless mode at the same resolution. Use Dota 2's own frame-rate limit when available and choose a value the PC can hold steadily.
6
Remove old launch commands
Open Steam Library, right-click Dota 2, choose Properties, and remove copied performance commands before testing. Old -high, -dx9, and configuration-pack advice can create new problems or no longer match the current client.
7
Update and repair Dota 2
Close unneeded recording, browser, and download apps, install the current stable graphics driver, and restart Windows. Verify the Steam files if Dota 2 alone remains slow or unstable.
If Dota 2 will not start, Valve recommends trying -autoconfig first and -safe second, one at a time. Remove the temporary command after the game opens so you can change Video settings normally.
If FPS stays steady but the network display shows high ping or packet loss, troubleshoot the connection instead of lowering render quality again.
If only large team fights slow down, repeat the same demo or bot sequence and lower effects or shadows before reducing texture clarity.
