Dotabod GSI FPS Issue Summary

Problem Statement

The Dotabod integration causes cyclical FPS drops in Dota 2 due to the GSI configuration. Multiple streamers (ODPixel, Gorgc, and potentially Arteezy) have experienced this issue where FPS drops significantly every few seconds in a regular pattern.

Key Findings

• The issue is caused by the GSI configuration file that Dotabod uses to get game data
• Removing the GSI folder completely fixes the FPS drops but breaks Dotabod functionality
• Modifying the buffer and throttle values in the GSI config can reduce the severity of FPS drops
• ODPixel found that setting buffer: 0.0 and throttle: 5.0 helped minimize the issue
• The FPS drops appear to be caused by Dota 2 taking resource-intensive snapshots of game state

Current Default Configuration

{
  "uri" "${process.env.NEXT_PUBLIC_GSI_WEBSOCKET_URL}"
  "timeout" "5.0"
  "buffer" "0.5"
  "throttle" "0.5"
  "heartbeat" "30.0"
  "data"
  {
    "abilities" "1"
    "buildings" "1"
    "events" "1"
    "hero" "1"
    "items" "1"
    "map" "1"
    "player" "1"
    "provider" "1"
    "wearables" "1"
  }
  "auth"
  {
    "token" "${userId}"
  }
}

Tested Alternative Configuration

"timeout" "5.0"
"buffer" "0.0"
"throttle" "5.0"
"heartbeat" "30.0"

Additional Notes

• The issue appears to be on Valve's side with how the Dota 2 client handles GSI data collection
• There's concern that increasing throttle/buffer values too much might cause missed events or delayed Dotabod functionality
• The FPS drops might be less noticeable if players don't have FPS counters visible
• A dual PC streaming setup won't fix this particular issue since it's on the game client side
