....D3D doesn't work well with GPL and ATI cards.

On two systems (XP with GeForce Ti4200, later ATi X1950Q; and Vista with GeForce 8500GT, now Ati HD5670) I've noticed no performance differences between D3D and OGL.  I have noticed graphic differences, OGL tends to have better color but D3D has better clarity.  But on both systems, with either card, shadows on the track surface are purple with OGL;  I've yet to find a solution to this so use D3D ...where the "vcr" buttons in full screen replay disappear when I press them.

Just an update to this thread to say that the latest AMD driver 14.4 version seems to cause problems with the OpenGL2 rasteriser in GPL. If you're getting a black screen when switching between the GPL menu and the driving or replay screens but can hear engine sounds and can  use Alt-Control-Delete to launch Task Manager to switch them manually, then you probably need to roll your drivers back.

I'm running OpenGL version 6.14.10.12618 from driver packaging version 13.251-131206a-165817C-ATI with no problems.

Same problem here, so thanks for the work around. Had hoped I could just fiddle with the settings but no joy

Just to keep this thread up to date, it seems the latest AMD drivers (August 2015) fix the OpenGL problems with GPL

Thanks Rich. Having got it working I have been reluctant to change anything, so it is good to know that I can switch to the latest drivers in case of need by any other software and not kill GPL in the process!

After giving up long ago of ever getting OpenGLv2 to work with Win7 at 2560x1440 resolution without producing a screen-freeze.............I found this reference from Fat Rich as regards the ATI driver version 6.14.10.12618 and decided to uninstall my much newer ATI driver and to install version 6.14 and just wanted to say thanks so much to FR ............because it worked!

A short story about grafic card drivers and gpl from my side...It seems to match at this place. I hope someone find a solution for equal problem I have had.

I have run gpl from 2008-2014 with my Vista PC/Inter Core2 2.66GHz/NVIDEA Geforce GS9500GS without problems - it means with 60fps and complete pribluda all the time - only at such tracks like SPA67 at the pits maybe 55fps, all other tracks continuos 60fps.
In the later years I was wondering that many people says: "I can't use the 60fps patch. Unfortunately my PC is to old."
In 2015 I make a gpl pause.
In 2016 I came back to gpl. Unexpectedly I had with the same gpl grafic options like before (oglv2) only about 25fps if I was driving (if I stand at the pits I had 60fps). I tried rastd3d7v2 and had all the time only about 45fps. If I had deactivated same pribluda displays I had 5-10fps more, but at no time 60fps.
I was perplex: What the devil  happened during my abstinence 2015?
After two weeks speculation I found the solution: In 2015 I had tested the rFactor2 and GPBikes demo. Both don't run with the old grafic card drivers - because that I have restored it (to version 340.52).
I changed to the old grafic drivers from 2008 (version 180.48) and since than gpl run stable with 60fps like before.

After that adventure I believe, if people say they have to old PCs for the 60fps patch in reality they have to new PCs in the most cases.

You are absolutely right Olaf!
I have some older AMD GPU's HD5770-6870-7970 and they all run best on older drivers, 14.4 is save and in my case I take the last CCC 15.7.1.

Now I bought an NV GTX960 to run it with Linux mint18 with the proprietary NV drivers.
It runs fine under linux as this driver is made for OpenGL, but in W7 I have a much worse picture using the recent driver.

Maybe someone with a NV GPU of this generation can give me a hint wich driver to use best?

Borderless monitors and GPL ... Is it possible?

Thanks.
