FileFlex Desktop application can take advantage of available GPUs on your system to distribute the processing load between the CPU and the GPU to get better performance.
Enabling GPU Accelerator helps in processing and you can expect to see improvement in the time taken to load the document for preview.
This can be enabled by doing a mouse right click on the native desktop application context menu.
Please note, not all GPU cards support accelerated rendering.
In case your GPU card doesn't support accelerated rendering, then you may see issues in using the FileFlex application and this option should be disabled by visiting the same menu.
You can check your driver settings to see if GPU acceleration is supported. If not supported you may not view the FileFlex application interface clearly.
If you encounter that issue, you can perform mouse right-click and disable this option.
Any change in the setting will require the FileFlex application to restart.
