# Computer Performance Performance problems inside a Vagon Computer are not the same as connection problems. The stream can be smooth and the latency low while the apps you run still feel slow. This guide covers what to check when the bottleneck is the computer itself — the CPU, GPU, memory, disk, or the application's own configuration — rather than the network between you and Vagon. If the stream itself is laggy or disconnecting, start with the connection guide instead. {% content-ref url="/pages/RAZObY49RDgKOCsGaOwW" %} [Connection Performance](/computer/troubleshooting/connection-performance.md) {% endcontent-ref %} ## Identify Where the Bottleneck Is Before changing performance tiers, narrow the issue down to a specific resource. * Open **Task Manager** inside the Vagon Computer and watch the Performance tab while reproducing the slow workload. * **CPU pinned near 100%** during work: the CPU is the bottleneck. Look at whether the application supports multi-core processing and whether it is enabled. * **GPU low while rendering is slow**: the application is most likely running on the CPU. Turn on GPU acceleration in the app preferences. * **Memory pinned near the tier limit**: raise application memory limits, close other apps, or move to a tier with more RAM. * **Disk activity sustained at 100%**: large project files or scratch disks are saturating storage. Move work to a different folder or upgrade your storage option. * **CPU, GPU, memory, and disk all look idle but the app feels slow**: this is usually a stream-side issue. Switch to the connection performance guide. ## Upgraded Performance Still Feels Slow A higher performance option gives your Vagon Computer more CPU, GPU, and memory, but many applications do not use those resources by default. If you upgraded and saw little improvement, tune the application itself. * **Enable GPU usage.** Many apps default to CPU rendering. Turn on GPU acceleration in the preferences of tools like AutoCAD, Blender, Premiere Pro, and After Effects. * **Enable multi-core usage.** Some applications support multi-threaded rendering or simulation but ship with single-core defaults. Enable parallel processing where the app offers it. * **Raise memory limits.** Several creative apps cap their own memory usage. Increase the limit in preferences so the app can use the RAM available on your performance tier. * **Check application-specific tips.** Vagon publishes Performance Suggestions in the dashboard for Blender, Premiere Pro, After Effects, Houdini FX, and others. ## Quick Wins Before Upgrading Before paying for a higher tier, try the cheaper fixes: * Close background processes and browser tabs inside the Vagon Computer. * Restart the session. A fresh boot clears anything stuck from the previous session. * Check Performance Suggestions in the dashboard for the application you are using. * Verify the application is up to date — new versions often fix performance regressions. ## Choose a Higher Performance Tier If the resource bottleneck is real and tuning the app does not unlock enough headroom, move up a tier. * GPU-heavy workloads (3D rendering, game development, video effects) usually benefit most from moving to a Fire-series tier. * CPU-heavy workloads (simulation, code compilation, batch encoding) benefit from tiers with higher core counts. * Memory-heavy workloads (large compositions, large datasets) benefit from tiers with more RAM. Review the available tiers and what each one targets before switching. {% content-ref url="/pages/5eC8iMR1VM0vuyIqNBEN" %} [Performance Options & Specs](/computer/features/performance-options-and-specs.md) {% endcontent-ref %} {% hint style="warning" %} Switching to a higher tier changes the hourly cost of the session. Confirm the tier in the dashboard before starting the computer. {% endhint %} ## When to Contact Support Contact support if performance is still poor after the steps above. Useful information to include: * The application and version you are using. * The performance tier the session is running on. * Which resource is pinned in Task Manager. * What you have already tried (GPU acceleration toggled, multi-core enabled, memory limit raised, tier upgraded). ## Next Steps {% content-ref url="/pages/5eC8iMR1VM0vuyIqNBEN" %} [Performance Options & Specs](/computer/features/performance-options-and-specs.md) {% endcontent-ref %} {% content-ref url="/pages/RAZObY49RDgKOCsGaOwW" %} [Connection Performance](/computer/troubleshooting/connection-performance.md) {% endcontent-ref %} {% content-ref url="/pages/fjJUvWUFqRo7MaD13CyM" %} [GPU Driver Issues](/computer/troubleshooting/gpu-driver-issues.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
