Having trouble with your hardware?
Are you struggling with that one function in XVR?
Don’t worry, just ask Tjin!
In this new section, XVR Helpdesk Specialist Tjin Yoe Li answers practical questions from users.
Tjin: "We are aware of this issue. We are working on a definitive fix for this issue, which we expect to be released in XVR On Scene 2017. If you need a quick fix before that, please contact us and together we will find a solution for this issue."
“This issue might have several causes:
- Your licence has expired. Please check the licensing date on the computer, to do this, open the XVR Control Settings, select Home and then Settings. You will be able to check the licence date here. If it has expired, please contact me!
- A wrong licence has been installed. Please contact me!
- You do not have the full version of XVR. To check this, go to the folder C:\Program Files (x86)\E-Semble\XVR2016. The full version of XVR is around 23 GB. Please contact me if you want the full version.”
"We advise that hardware should be upgraded every three years to run XVR On Scene properly. This way, the continuity of your training and simulation setup will be guaranteed.
There is a direct relationship between XVR On Scene and the computing power of hardware. The more objects and tasks you put in your scenario, the more computing power you will need. In other words, the only limit to a scenario, is the hardware that is being used. If you feel like that limit has been reached, you have a couple of options. Try and build scenarios more efficiently or upgrade the computer to the recommended hardware specifications. Our Service and Support department are always ready to advice you on these matters.
Tips for building efficient scenarios
If you want to try and make a more efficiently build scenario, please try the following tips.
- Use the image creator in order to use less different elements
- If you are using paths, try to use as little nodes as possible
- Try and limit the use of avatars
- Only add extra detail to the area’s the participant is likely to walk
- If details are only important from the participants view, make use of ‘Hollywood facades’.
If a computer was bought according to our recommended hardware specifications, XVR On Scene will not be limited by the hardware within three years. After three years of intensive use, complex scenarios might not run as smoothly as they should.
Upgrading hardware doesn´t mean throwing out the ‘old’ hardware. If the hardware was bought according to our recommendations you bought state of the art hardware to run XVR On Scene. After three years that hardware is still very much able to run less intensive XVR software such as Resource Management or Crisis Media. If you plan to re-use the hardware for regular office work, it might even get an extra 2 to 3 years out of the hardware. This is also how we work at the XVR offices.
It could also be a Firewall issue. Please see the Windows Firewall exception list in the configuration screen, try and locate the XVR program, and add it as an exception. This might be needed to be done after installing XVR, both full versions and updates.
You might also be working with wrong IP addresses. IP addresses need to be in the same range, or being set up as automatically. Please go to Windows Network Centre, go to the network adapter and find the used adapter. Here, you can check if the IPv4 address is set to automatically. If not, please see if the IP addresses are unique for each computer, but within the same range. For example; computer 1 could be 192.168.1.1, and computer 2 could be 192.168.1.2. This allows the computers to directly connect with each other or through a switch. If you have any questions or the student still has no environment on his computer, please contact me.”
Tjin: "A 4k screen requires 4 times the CPU capacity, as it has 4 times more pixels. Running XVR on a 4k screen means the CPU is unable to perform well enough. The solution is to downgrade the resolution on the screen. Untick the ‘Start XVR full screen’ in the XVR Control Panel settings page. When starting XVR in full screen it will auto adjust to the current resolution.
If the problem persists, please contact me."
Tjin: “Usually this means that the graphics card isn’t supported in the current XVR software. We recommend using a NVIDIA GeForce graphics card. AMD/ATI video cards are not supported with the regular version. To get XVR working on AMD/ATI cards, you could downgrade the XVR software to a 32 bit version. To do this:
- Go to C:\Program Files (x86)\E-Semble\XVR 2016\XVR 2016\Support\32-bit
- Copy the content (the folder XVR_DATA and XVR.exe)
- Paste and replace the files in C:\Program Files (x86)\E-Semble\XVR 2016\XVR 2016
If the problem persists, please contact me.”
Tjin: “If the joystick doesn’t work, it may be that the wrong input device is selected. To check this, do the following:
- Start XVR
- Go to settings (bottom right corner, the two cogs) (in student mode; alt+p)
- Go to the second tab; gameplay.
- Check if the correct joystick is selected as input device
Also, if you are using alt+tab to switch between different screens, the Alt button might ‘stick’ as an input. This causes the joystick to have another control on it. To fix this, press Alt one more time to correct this.
Another issue could be that the joystick causes immediate movement. This means the joystick isn’t calibrated correctly. When you plug in a joystick, or even when the computer is booting up or if you have moved the joystick during calibration, the calibration will be off and you will see movement when the joystick is in neutral position. To fix this, close XVR, unplug the joystick and plug it back in. Restart XVR again.
If this doesn’t work, please try switching to a different joystick if you have one. The joystick might simply be broken.
If the problem persists, please contact me.”
Tjin: "A lot of users like to add object with the object/image creator to make their environments more recognizable and immersive for their students. I have two tips to make sure your computers can load up these scenarios faster:
- Large images can put a heavy load on the network in XVR. XVR automatically scales down the image to 256 by 256 pixels so network traffic will not be overloaded. However, this scaling down will cause the computer to take long to load the scenario. Therefore, to reduce the loading time, I recommend keeping the image size at or near 256 x 256 pixels. This will reduce loading time, with little to none effect on the seen image quality.
- Some users like to copy and paste an image to create a longer image. Each copy is loaded as a new image and will add extra loading time. In most cases, having one larger image with these repetitive elements already in place, will significantly reduce loading time."
