SL is highy demanding to your graphics card, like no any other program. You may be fine for everything else, but you might have to check if any drivers updates are available from your graphics card manufacturer's website.

What to do if you're having graphics problems

 

Important: Always carefully follow the manufacturer's instructions. Consult the websites below for details and support.

On Windows:

• ATI/AMD drivers
• NVIDIA drivers
• Intel drivers

The following procedure, called a clean install, will often fix problems related to graphics cards and drivers:

1. Download the latest graphics driver from the chipset manufacturer (ATI, Nvidia, or Intel), not the maker of your graphics card or computer. Save the file where you can easily find it, but do not install it yet.
2. Run Windows Update and make sure your system is fully patched.
3. Reboot your computer and enter Safe Mode by pressing F8 at the Windows logo screen.
4. Uninstall your old video driver. On Windows XP use Control Panel > System > Hardware > Device Manager (steps will be different on other operating systems). Then open Display Adapters, right-click and choose Uninstall.
5. Reboot your computer.
6. If Windows displays a message that it found new hardware, do not let it automatically install drivers. Instead, run the installation program that you downloaded in step 1.
7. Reboot your computer

You should now have a clean version of your video driver. If this doesn't solve the problem, try searching the Issue Tracker for known issues.

Note: Intel Extreme graphics are not compatible with Second Life. It may be possible for certain configurations of hardware and software to successfully run Second Life while using Intel Extreme graphics; however, these configurations are inherently unstable.

Note about NVIDIA drivers

NVIDIA graphics cards may cause driver-related problems. After installing the latest NVIDIA drivers, the Second Life® Viewer may crash with an error message that states: "Second Life is unable to run because your video card drivers did not install properly, are out of date, or are for unsupported hardware." This appears to be a problem with the NVIDIA drivers' initial installation: the first time the install process is run, something fails silently — a file or set of files doesn't copy properly, but the installer doesn't give you any notice that something went wrong.

There is a solution: ensure that all of your applications are closed, and install the NVIDIA drivers again. For some reason, the drivers almost always install correctly the second time.

If these steps do not solve your problem, please see NVIDIA's Driver Installation Hints.

If you press Ctrl-P  to get into your options, then under graphics, try to turn off the checkbox "Basic shaders".  Push apply and see if the annoying flashes go away for you.

Do it anyway. It's always good to have your machine up to date.

^^This! I'm with Orca on this one. :smileyhappy:

[harmony Palmira]

ok and for this step  num 4  i have in my pc the intel graphics or ati/amd wich one should i delet b4 install the new driver coz i downloaded the new updat for the ati card without deleting the old one and nothing change .

[Vegro Solari]

You have the same problem as me, that's how I knew which box you need to uncheck.   The problem comes from the Intel driver (intel graphics).  If you have a separate graphics card by ATI, maybe you can get rid of the intel graphics driver and then things will work properly.

As far as I know Intel still hasn't fixed this flashing stuff in their driver. It started in like October last year!

Things do look nicer in SL if that box is checked, so good luck!

[harmony Palmira]

do u mean i have to remove the intel from my pc ! i dont think thats can be ! then other things in other program or the system in my pc will got alot of fault ! idk .but if u fix ur problem wich is same as mine can u give me the tips for that maybe somthing like switch only the amd to work only for secondlife  or somthing ?

[Vegro Solari]

Harmony, gawd no, you don't need to remove anything from the PC - it's just the software. You go to "Add/Remove Programs" in your control panel, look for the "Intel Graphics Driver", and tell it you want it uninstalled.

You can do this with no issues since you have your ATI videocard.  The Intel driver is for the crappy Intel graphics that come with PCs for people who don't have a real separate videocard.

In case you ever want it back, you can always install it again.  Good luck!

Back in Oct. I got in touch with the Firestorm team and they are going to have a fix for this flashing in their next release (supposedly soon), but the current one still has it. I just use it with the box unchecked for now!

I have tried every solution I have found on here. I've updated graphics driver, turned off shaders, and turned off VBOs. What other options do I have.

[Amphei Jierdon]

I got the same problems and also have tried everything. 

 

Is there really no other solution than switching off the basic shaders???

 

Switching off basic shaders really looks ugly

[Whirly Fizzle]

There are many different causes of screen flashing.

In the top menu bar of the viewer, go to Help -> About Second Life / Viewer name, click the "Copy to clipboard" button & paste all your system information into a comment here.

Hi Whirly, 

thanks for trying to help, but after an almost sleepless night of Google research, I found the solution:

My laptop has 2 graphic processors, an Intel (for normal stuff) and a nVidia for high performance graphics. The automatic selection chose the Intel processor for Firestorm... and that was not strong enough, so it caused the flickering, and I had to switch off the Basic shaders... which really doesn't look nice. 

But in the nVidia control panel, I can choose manually for every single application, which graphic processor it should use.... and this is what I did... the nVidia graphics processor of course for firestorm.

Since I did this, Second Life really displays nicely, with basic shaders on and even on crowded sims, I get fps-rates of ~25 with graphics quality set to "ultra" and all shaders enabled up to ambient occlusion.

 

So I am happy again and enjoy my SL :)

Great!

If you have one of the new Intel Skylake processors with Intel HD 500 graphics, you were probably getting bitten by BUG-10819 - [intel HD Graphics 500 series] Screen flashes with certain graphics settings when any worn rigged mesh is in view textured with a diffuse texture set to alpha blending mode.

>>If you have one of the new Intel Skylake processors with Intel HD 500 graphics

 

I got an Acer Aspire V15 Nitro Black Edition VN7-592G and I think, this has a Skylake Processor. But as I said, atm I am very happy. I had set graphics to "ultra" and on a crowdes sim got ~55 fps with and > 100 fps with shadows turned off. 

The only drawback is that the laptop gets a bit warm, but I think, this is normal.
