In case you don’t know, there is a feature in Windows 10 computers that allows them to function a lot better. This feature is called Full-Screen optimization and it is enabled by default for several applications such as games and video players. If enabled, the Full-Screen optimization feature enhances the video playback and gaming by simply putting the CPU and GPU process as a priority. However, there are times when it can also result to a drop in the frame rate or FPS while in full-screen mode. And of course, the obvious solution to this dilemma is by disabling the Full-Screen optimization feature which is why Microsoft took action and removed this feature themselves in the recent Windows 10 Update releases. However, there is another way for you to enable it back or disable it yourself if you haven’t installed the recent updates yet and there are plenty of ways you can do both. All you have to do is follow the options given below carefully.

Option 1 – Try using Windows 10 Settings

If you haven’t installed the recent updates yet and all you have are the earlier releases, then this method would suit you.

• Open the Windows 10 Settings app.
• Next, navigate to System > Display > Graphics Settings or Advanced graphics settings.
• From there, uncheck the “Enable Fullscreen optimization” option if you want to disable the feature, else just keep it checked.

What is RTX

Nvidia GeForce RTX is a high-end professional visual computing platform created by Nvidia, primarily used for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production. Nvidia RTX enables real-time ray tracing. Historically, ray tracing had been reserved for non-real-time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering. RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows, and reflections. RTX runs on Nvidia Volta-, Turing- and Ampere-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.

Advantage in games

With incredible lighting and shadows, reflection, better smoke, and water effects, and more, RTX has managed to place awesome real-time effects on your desktop all that’s to Nvidia technology behind it. Of course, in order to harvest this kind of technology and features game itself needs to support and have RTX in it, you can not turn RTX in just any game, the game itself must have technology build in it.

Distributed Component Object Model or DCOM is a module on Windows computers that allows computers to run programs over a network to another computer. It is a software component from Microsoft that allows COM objects to communicate with each other while that program is remotely running over the network. The COM Model is another extension of the DCOM model which both work together in order for the intended task to be executed. To make this module work, there are three components needed such as the Class Identifier or CLSID, the Programmatic Identifier or PROGID, and the Application Identifier or APPID. However, DCOM does not always work as expected as it could still encounter some errors. One of them is error 1084. Because of this error, the execution of programs in a remote computer on the network would be interrupted. So if you encounter the DCOM error 1084 when you try to start a service like running the DISM tool or in other scenarios on your Windows 10 computer, then this post could help you. Refer to the instructions given below to start troubleshooting the problem.
