With its Rift model, Oculus set itself as a big player in VR. Now the company is slowly bowing out of the dedicated, tethered VR headset with its latest Quest 2 designed to primarily be a standalone headset.
In case you do not know, tethered headset means that the headset itself is connected to your PC and is using its power to drive your VR experience.
Now technical specifications of Quest 2 are pretty OK and it can drive stuff pretty decently and if you want you can purchase the dedicated cable to connect it to your PC for the full experience of games requiring more capable hardware.
Oculus Quest 2 is the cheapest headset on this list and with its stable performance, is highly recommended.
Although the headset itself is nothing revolutionary or special its controllers are. They can track individual finger movements, making games (that take advantage of them) much more immersive than the standard trigger grips on other controllers.
The Index's higher refresh rate makes for smoother action, as well, which is another nice bonus. If you already have an HTC Vive or Vive Cosmos Elite, and their base stations (not the regular Cosmos), you can buy only the controllers.
The PlayStation VR is compelling thanks to Sony backing its development, plus the PlayStation 4's affordability and availability compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles).
Not really the best of the bunch but still one of the top ones for console gaming. Sony is working on a new PlayStation VR system for the PlayStation 5, with redesigned controllers. The new headset hasn't been revealed yet, but the company has released a preview of the new controllers.
HP headset is one which you get if you want the best image quality in VR headset, sadly controllers did not follow the same quality of headset itself. But this is still a pretty decent headset overall and worth the purchase.
HTC's Vive Cosmos is the upgraded version of the Vive. It features a higher resolution and replaces the external base stations with outward-facing cameras for motion tracking. It's a comprehensive package for whole-room VR.
HTC recently released the Vive Pro 2, a high-end VR headset targeting both enterprise users and consumers. This new headset features a 2,448-by-2,448 resolution display for each eye, making it the highest-resolution headset currently available. It's also more expensive than the Cosmos Elite.
Sadly one thing that is bringing this headset down is the price. Some users wanting to upgrade to Windows 10 from Windows 7 or Windows 8.1 experienced errors with installation. One of these errors is CPU Not Compatible. When you click and run the “Get Windows 10” from your system tray bar, you’ll receive the “CPU is not compatible with Windows 10” error. When this happens, it might be good to check if there’s a bug or if your NX feature (a requirement for the Windows 10 installation) is enabled.
Error CausesThe “CPU is not compatible with Windows 10” error normally occurs when:
To successfully upgrade to Windows 10, your CPU must support Physical Address Extension (PAE), SSE2, and NX features. If any of these features are not activated on your system, it’ll cause the CPU not compatible error. However, some users still reported experiencing this error even though their CPU has these features activated. Normally, this is due to the bug that Windows acknowledged.
If any of these two scenarios apply to your computer, the following methods will help you fix the problem:
The bug applies to some Windows 7 and Windows 8.1 systems. The bug occurs when the “Get Windows 10” app fails to recognize CPUs as being compatible. This produces a false negative result with a message, “Here’s why Windows 10 cannot be installed on this PC: The CPU isn’t supported”. To fix this bug, Microsoft released an update.
Unfortunately, the patch update (KB2976978 for Windows 8/8.1 and KB2952664 for Windows 7 SP1) to fix the bug may not be automatically downloaded to your computer. If this is the case, you need to verify first if the patch was installed correctly. To do this, follow the steps below:
A major requirement for Windows 10 upgrade is for the CPU to have Physical Address Extension (PAE), SSE2, and NX features enabled on your system. If you receive the CPU not compatible error, one possible cause is that any of the mentioned features are not available OR not enabled on your system. Here’s how you can fix this:
If changing the settings in your BIOS doesn’t do the trick, your final option is to force enable the NX bit in your Windows system. However, this is only applicable IF and ONLY IF your CPU does support it. To force enable NX bit, do the following:
RegClean Pro is a program developed by Systweak Inc. RegClean Pro cleans such invalid registry errors using its advanced scan engine. It not only fixes invalid registry entries, it also defragments the registry, keeping it streamlined for smoother system performance.
RegClean Pro defines auto-start registry entities that allow the program to run each time the system is restarted, it also adds various Scheduled tasks in Windows Task Manager in order to launch the application at various times. This application has been found bundled up with various other potentially unwanted applications, also several anti-virus programs have detected this application for optional removal.
Windows will then go to the accounts settings page. Within that page, click on the Family & other users to open the setting for the chosen section on right. On the right settings, screen navigate to the lower section and click once with the left button on add someone else to this PC
When add someone else to this PC is clicked, pop up window will appear which will ask you to provide the persons email address and later on the password of his/her Microsoft account, after the required information is provided you are done, a new user has been added and he can use his Microsoft credentials on the login screen to use this computer.
This will open yet another pop-up giving you the option to create a Microsoft account for this person, to use a phone number instead of a Microsoft account, or to create a new email address for the user. Any of these options will create a new user for this computer with provided credentials but there is the last option at bottom of the pop-up which will allow you to create a local user only without a Microsoft account. This user will be able to use this computer, will not be able to transfer his document through various devices like he/she would if using a valid Microsoft account but it could use the computer and personalize it fully to his/her liking.
Once the link is clicked, you will be presented with a floating window requiring you to input needed information in order for the account to be created. You will need to provide username, password, and answers to 3 security questions.
Once all information has been provided, click on next and your new non-Microsoft local user has been created. Now when you click on Family & other users you will see that Windows has added a new user with the provided name to this computer. If you wish, you can add another user in the same manner, following the previous steps. Microsoft Windows does not have a limit for how many users can be on one computer so feel free to create as many as you like.
Click on Change account type.
Under account type, you will have the option to promote this user to an administrator if you wish or you can leave it as a standard user.
Most of the time running applications with typical settings is fine but from time to time we might have some applications that will require running with administrator privilege in order to work properly. In this case, it is very easy to do it, you just right-click and choose run as administrator.
Although a very easy solution, it can be quite annoying if running the app is on a daily basis or even more times per day. If this is the case then right-clicking and choosing to run as administrator can be a daunting task, sometimes you can even forget to run it like this in heat of work and some unforeseen consequences might occur.
Luckily there is an easy hack so you can open the chosen application each time as an administrator with a simple double click each time.
