Assetto Corsa
AC's community says it: packet loss is more damaging than raw ping. Even 1–2% loss causes cars to jump and snap. If you have a phone and WiFi, that's two connections — PingAim routes acs.exe through whichever delivers the cleanest packets to your race server. Your stream, Discord, and household traffic go on the other one.

Why ping matters in Assetto Corsa
Latency sensitivity HighPing noticeably shapes the experience.
Assetto Corsa has no rollback netcode and no lag compensation. Position updates from the server arrive at CLIENT_SEND_INTERVAL_HZ intervals (typically 15 Hz = 67ms apart). When a packet is delayed or lost, the client predicts car movement; on packet arrival the car snaps to its true position. This is AC's characteristic 'car jumping' or 'teleporting'. The community consensus is that AC is extremely sensitive to packet loss — even a stable 150ms ping with clean delivery is more tolerable than a 30ms ping with 1–2% packet loss, which causes constant position snapping. Sim racing makes this worse than FPS: braking points, turn-in timing, and close-quarters wheel-to-wheel contact all depend on knowing exactly where other cars are. Because AC connects directly to server IPs, ISP routing quality has direct impact with no intermediary relay to buffer it.
About Assetto Corsabackground, studio, esports scene
Assetto Corsa (2014) is a PC sim racing game by Italian studio Kunos Simulazioni that remains one of the most-played sim racing titles a decade after release — almost entirely due to its massive modding community. The base game includes laser-scanned real-world tracks and officially licensed cars, but the real draw is an enormous library of community mods: thousands of cars, hundreds of tracks, and physics adjustments distributed through sites like RaceDepartment and AssettoCorsa.net.
The multiplayer infrastructure is built on dedicated servers run by the community. The official Kunos lobby (Kunos Server) lists all publicly registered servers, and players join via the in-game server browser. Content Manager, a free third-party launcher made by x4fab, has become the de facto standard way to launch and play AC — it provides a modern server browser with filters, favourites, and password support, as well as easy mod management.
AssettoServer is a popular open-source alternative dedicated server implementation (originally for freeroam/traffic servers) that has also become widely used for custom racing sessions with its own physics validation. The game uses a configurable tick rate (CLIENT_SEND_INTERVAL_HZ) and direct UDP/TCP connections — no relay infrastructure. AC has no anti-cheat at any level, making it fully compatible with network optimisation tools.

PingAim detects Assetto Corsa automatically
No manual config. PingAim identifies Assetto Corsa by process name and routes it through your fastest connection using a kernel-level WFP driver.
When does PingAim help — and when doesn't it?
PingAim helps when...
- You have a phone with 5G/LTE — tether via USB for a dedicated AC connection with no household traffic competition
- You have both WiFi and Ethernet — route acs.exe through whichever pings lower to your specific race server
- You stream your races on Twitch/YouTube — OBS upload no longer competes with AC game traffic
- Your household internet is congested in the evenings when you race — phone tethering bypasses household congestion
- You have two ISPs or a dual-WAN router and want to pin acs.exe to the faster path
- Windows picks the wrong interface for acs.exe and sends race traffic over WiFi while Ethernet is available
- You connect to EU servers from outside Europe and need the cleanest possible routing path
- Your connection has intermittent packet loss (even at low ping) causing car jumping on community servers
Won't help when...
- You only have one network connection with no way to add a second
- Your single connection is already fast, stable, and low packet-loss to your chosen server
- Server-side lag: overloaded community servers with too many cars or insufficient CPU cause their own jumping independent of your network
- Mod checksum mismatches — if you see 'checksum error' on join, that is a mod version issue, not network
- FPS drops in heavy traffic — AC is CPU-bound on physics; frame rate issues are not network-related
- AI traffic stuttering in offline mode — fully local, no network involved
