According to widespread player complaints on Reddit, the Blizzard forums, and other communities, the rendering crash can occur without warning and makes enjoying the new free-to-play title a frustrating endeavor.

In this comprehensive troubleshooting guide, I‘ll leverage my expertise in PC gaming technology to help you get to the bottom of Overwatch 2‘s "Rendering Device Lost" error and restore smooth, uninterrupted gameplay sessions.

What‘s Causing Your Overwatch 2 Rendering Device to Get "Lost"?

When your Overwatch 2 rendering device stops working correctly, there are a few common culprits to blame for the crash:

Outdated Graphics Drivers

Keeping your Nvidia or AMD graphics card drivers fully up-to-date is crucial for avoiding game crashes. Newer titles like Overwatch 2 often expose bugs and stability issues in older drivers. For example, Nvidia users have reported the rendering crash on drivers older than 516.59.

Installing the latest Game Ready driver offered by your GPU manufacturer ensures maximum compatibility and performance for new releases.

Overloaded RAM

Having too many active programs and browser tabs eating up your system memory can lead to an Out of Memory (OOM) crash when RAM is exhausted. With only 2-4 GB typically allocated to games, overwhelming your RAM with other processes lets it quickly reach capacity.

When physical memory is full, your PC has to utilize the much slower virtual memory ‘pagefile‘ on your hard drive, which can cause stability issues and crashes. Monitoring your overall memory usage and closing unnecessary background tasks is key to avoid overloading RAM beyond its ~95% capacity.

Conflicting Apps Running in Background

Many common background apps have been found to directly clash with games and cause crashes or rendering errors. Conflicts in software hooks, proxies, overlays, monitoring tools, RGB lighting utilities, and more can disrupt rendering and lead to display device crashes in games.

Confirmed problematic apps include EVGA Precision XOC, Xbox Game Bar, Razer Synapse, ProxyCap, Discord, MSI Afterburner, f.lux, RTSS, and Nvidia‘s own Broadcast app. Fully closing or uninstalling these before launching Overwatch 2 can prevent conflicts.

Overheating Hardware

Excessive heat buildup on components like your GPU or CPU can force them to throttle performance and eventually crash when they hit temperature cut-off points around ~100C.

Factors like accumulated dust blocking cooling, poor case airflow, faulty fans, dried thermal paste, or simply demanding games overloading your hardware can cause overheating. Monitoring your temperatures and taking cooling improvement or hardware upgrade steps may be necessary.

Now that we‘ve identified what causes the "Rendering Device Lost" error, let‘s go through effective troubleshooting steps to fix it in Overwatch 2 and get back in the game!

Troubleshooting Your Overwatch 2 "Rendering Device Lost" Problem

Update Your GPU Drivers

As mentioned earlier, the first thing to try is ensuring you have the latest Nvidia or AMD graphics drivers installed for your card. Outdated drivers are a common source of game issues.

For Nvidia GPUs, open the GeForce Experience app, log into your account, and check for updates on the Drivers tab. For AMD, head to the AMD site and use their auto-detect tool or manually look up your card. Always perform a "Clean Install" when updating drivers to clear out old files.

Pro Tip: When installing new GPU drivers, always reboot your PC first into Safe Mode to fully clear any currently loaded driver files before installing the update. This avoids potential conflicts.

Uninstall and Reinstall GPU Drivers

If freshly updating your graphics drivers doesn‘t resolve the rendering crashes, take the more aggressive approach of completely uninstalling the current drivers and doing a fresh install.

A corrupted driver installation where files are missing or damaged can manifest as rendering problems in games. Follow these steps:

Download and run the Display Driver Uninstaller (DDU) utility.
Select your GPU vendor (Nvidia, AMD) and graphic driver version to fully uninstall.
Reboot into Safe Mode and run DDU again to clear remnants.
Reboot back into normal mode and install the latest driver from your manufacturer.

This "scorched earth" approach often fixes corrupted driver installations causing crashes like "Rendering Device Lost".

Close Resource-Hungry Background Apps

Press Ctrl + Shift + Esc to open the Task Manager and carefully look through all running processes and applications that could be consuming valuable GPU, CPU, memory, or disk resources in the background.

For example, web browsers, MS Edge, Discord, RGB lighting utilities like iCUE or RGB Fusion, monitoring apps like HWiNFO64, etc should all be closed before launching your game. This prevents them from starving Overwatch 2 of resources.

You can also disable unneeded Startup apps using Task Manager‘s Startup tab. Less programs launching when you boot up means more resources freed for gaming.

Update BIOS, Chipset, and Windows Drivers

An outdated motherboard BIOS or chipset drivers can potentially cause system instability and game crashes. Use your motherboard manufacturer‘s utilities to update the BIOS to the latest available version.

For the chipset, head to AMD or Intel‘s site to find the latest chipset drivers for your processor and install them.

Finally, be sure Windows is fully updated by running Windows Update and checking for any available driver and OS updates from Microsoft. Keeping Windows patched maximizes game compatibility.

Improve Cooling and Monitor Temperatures

Use a system monitoring utility like HWiNFO64 or MSI Afterburner to keep an eye on your hardware temperatures when gaming or doing intensive graphical tasks.

Look for any components like your GPU or CPU exceeding ~85C, which can indicate cooling issues leading to possible thermal throttling and crashes.

Improving airflow with additional case fans, reseating or upgrading CPU coolers, replacing thermal paste, and blasting out dust buildup can all help lower temperatures.

You can also adjust your GPU‘s fan profile using utilities like MSI Afterburner to ramp up fans faster and improve heat dissipation if needed.

Pro Tip: Disable any GPU overclocking if enabled when troubleshooting rendering crashes, as this puts additional stress on your graphics card.

Scan for Malware and Viruses

Sometimes malware or viruses that have infected your system can interfere with games in various ways, including hooking into GPU processes and disrupting rendering.

It doesn‘t hurt to perform a full system scan with your antivirus program or the built-in Windows Defender to check for any potential infections. Quarantine or remove anything malicious found.

Try Lowering In-Game Graphics Settings

If the above steps haven‘t resolved your Overwatch 2 crashes, try reducing the graphics settings in-game to lower the load on your GPU.

Lower resolutions, disabling taxing settings like shadows and anti-aliasing, capping frame rates, and using medium graphics presets can help reduce the chance of rendering crashes by easing the GPU workload.

Test and Upgrade Hardware

As a last resort, you can isolate if the crashing issue is being caused by a faulty component like the GPU, RAM sticks, or power supply by swapping in known-good spares for testing.

Stability testing utilities like Furmark and memtest86 can also help identify faulty hardware that may be causing problems.

Ultimately, if your system is aging and still seeing rendering crashes after trying the above fixes, upgrading to modern hardware like a new GPU may be required for stable Overwatch 2 performance.

Preventative Measures and Maintenance to Avoid Rendering Crashes

Here are some proactive troubleshooting and maintenance habits to practice that can help minimize rendering crashes in Overwatch 2:

Update GPU drivers regularly – Don‘t let them become severely outdated over many months. Update promptly when new Game Ready driver versions are available.
Monitor temperatures – Use HWiNFO64 or Afterburner to ensure your components aren‘t overheating from insufficient cooling.
Close unused background apps – Free up precious RAM and other resources that the game needs by closing other programs.
Disable unnecessary startup apps – Prevent extraneous software from launching at boot via Task Manager.
Keep Windows fully updated – Regularly install the latest Windows updates for optimal compatibility.
Clean dust buildup – Compressed air and dusting computer case intakes prevents overheating issues.
