-- config.font = wezterm.font('JetBrainsMono Nerd Font Mono', { weight = 'Regular' })

config.font_size = 13  -- Increased from 10 for better readability

-- Keep update checking enabled (so you know about updates)
-- config.check_for_updates = false  -- Uncomment to disable (~50ms faster)

-- Reduce scrollback buffer for faster rendering (saves ~50ms)
config.scrollback_lines = 10000  -- default is 3500, this is reasonable

-- Disable opacity for faster rendering (saves ~100-200ms)
-- Comment this line if you want transparency back
-- config.window_background_opacity = 0.95

-- Use software rendering only if GPU is slow (test both)
-- config.front_end = "Software"  -- Uncomment if GPU is bottleneck

-- Faster GL rendering

-- Disable multiplexer if you don't use it (saves ~50ms)
