If the game refuses to start, the first place to look is your GPU drivers — outdated drivers are responsible for a huge chunk of launch failures. Update them, then verify the integrity of game files through Steam or the Epic Games Launcher. Also check that your system meets the minimum requirements: ARC Raiders demands a modern DirectX 12-capable GPU.
Latency issues in a co-op shooter like this can make the game unplayable. Try these steps:
Random crashes mid-match usually point to one of three things: overheating, RAM instability, or a driver conflict. Monitor your GPU and CPU temperatures with MSI Afterburner or HWiNFO. If temps are fine, run a RAM stress test with MemTest86. Also try lowering in-game graphics settings — some shader combinations trigger driver crashes on specific hardware configs.
If you can't get past the login screen, first check whether the game's authentication servers are having issues — the official ARC Raiders social channels usually post status updates. Clear your credential cache by logging out of the launcher completely and back in. If the error code mentions a token failure, deleting the local config folder and re-authenticating tends to fix it.
Blurry textures or missing geometry mid-game almost always mean the game files are corrupted or the shader cache needs to be rebuilt. Run a file integrity check through your launcher. Additionally, delete the shader cache folder — the game will rebuild it on next launch, which takes a few extra minutes but resolves most visual glitches.
If the matchmaking queue spins forever, the issue is often a firewall or NAT type problem. Open the required UDP ports for the game in your router settings, and make sure Windows Firewall isn't blocking the executable. A NAT type of 'Strict' will consistently break session joining.
