About Real-time Rendering
On the Render Studio tab, you can toggle the photo-realistic effect on or off by clicking 
Real-Time Rendering. In the Real-Time Rendering Settings dialog, modify the individual ray tracing settings or select a preset that sets the optimal ray tracing.

You can run Render Studio in both CPU and GPU mode. In GPU mode, the rendering process utilizes the GPU capability of the NVIDIA RTX cards to produce more samples in less time. If your system hardware supports GPU rendering, Render Studio runs in GPU mode by default. For more information on system and hardware requirements, see hardware release notes. Set the configuration option advanced_rendering_mode to cpu if you want to run the application in CPU mode.
Advantages of GPU rendering over CPU rendering.
• Speed: GPU with its modern architecture and algorithms calculates more samples and removes more triangles than CPU.
• Denoising: GPU rendering allows for a quick removal of noise from the rendered output.
• Scaling: Performance can be scaled up by using more GPU cores.
Denoise
When the application is running in GPU mode, you can use the Denoise command on the Render Studio tab to remove the noise in the rendered image in a fraction of a second. You can toggle the command on or off while the rendering process keeps progressing in the background. Denoise does not affect the sample rate or time. Use Denoise on complex geometries and textures that usually take longer to render the desired final image.
