Jagged edges & bugged shadows after videocard upgrade

Technical Problems SketchUp
1

I tried to use search, found some people who had this problem (Aliasing (jagged edges) with new graphics card & New card and SU15 and all of a sudden I have jagged lines and others). Tried everything and there is no fix for me.

I had GTX 650ti 1gb, everything was working great, but when I got GTX 980 it got really bad. OpenGL 4x anti-alias doesn’t help much and I really need same graphics as it was working before. Edges are jagged and there are weird lines coming out of shadows (on both videocards).

  • Nvidia control panel set to “Let the 3D applications decide”
  • I had clean driver reinstall
  • I tried to use old GTX 650ti on different PC but it has same problem!
  • OpenGL 4x anti-alias in settings http://i.imgur.com/2O9Ogri.png

Will really appreciate if someone can help me.

What does it says for OpenGL support version on the Details dialog for the new 980 card ?
Preferences > OpenGL > Details
Nevermind, I see you posted the screenshot. It says version 4.5.

BTW, the GTX 980 models are ranked 1, 4 and 17 at:

This extension provides a Shadow Strings Fix toolbar which allows you to toggle on and off a fix for this issue. While this may help eliminate shadow strings, it is possible that other visual artifacts will appear.

I have 4th one, GeForce GTX 980. But it’s the same with the 650. I tried to downgrade the video driver, nothing changed at all.

It might help if you post the Nvidia driver versions, that are showing the issues (so other people with that same driver or cards can compare.)

It fixed one problem, but now there is another - white outline in some places http://i.imgur.com/wfonLRM.png

My current driver 355.60-desktop-win8-win7-winvista-64bit-international-whql. I used 340.52-desktop-win8-win7-winvista-64bit-english-whql to downgrade.

There have been some reported issues with 64-bit Graphics drivers having issues with OpenGL. (Mostly AMD/ATI)

One of the standard solutions is to install the 32-bit SketchUp until these 64-bit graphics issues can be addressed.

I’m here again, with the same problem. 32bit didn’t do much, it only fixed shadows problem. I decided to get my old windows from Acronis backup and to check how it looks there.

Here is a bunch of before and after screenshots:

Before: edges+shadows on http://i.imgur.com/VkSCftA.png http://i.imgur.com/52pdzD9.png

As you can see edges are very clear and it’s important for me, since I use them as lineart in my drawings! Note that it’s 64bit version, shadows are not bugged and anti-alias is set to 0. I never touched this settings.

Now the most interesting part, I decided what if I will use 4x anti-alias. http://i.imgur.com/xzw0047.png

Quality went to how it look on current PC: http://i.imgur.com/YiFYXhj.png
I set it back to 0, but to my surprice it was all pixelated!! http://i.imgur.com/bXoxPWs.png

I saw that there is difference in “Pixel format”, after I changed settings to 0x anti-alias, first number become “63”, and it was “16” before, when it was looking good.

Maybe I’m wrong but I think it’s because of the “pixel format” thingy. Is there any way to force change it to 16?

What about your display ? Is it High DPI ? Do you have it set to a strange resolution ?

I tested it on pc with yiynova mvp22u (1920x1080) & Dell U2312HM 23" (1920x1080), and on another pc with Dell E196FP 19" (1280x1024). It’s default resolutions for them.

How can I copy OpenGL settings from other windows?
