Compile Error / Unknown Error

[Sliderpoint]

We had quite a few posts in the TAF thread and I saw this pop up in Pin Bot and Funhouse as well.  I thought I would make a topic for it to try to help people out.

The error pops up when you go to launch a table.

Compile Error: Unknown Error.  Sometimes a few of them.  Sometimes will end with Error:
Fatal Error: shader compilation failed! Unknown (0xffffffff: n/a) at c:\projects\vp10\renderdevice.cpp:802

After working with Toxie, he suggested I roll back my drivers and see if that helps.  It did,  I no longer get the errors.

I have an nVidia GTX 850M,  looking here:  https://www.nvidia.com/drivers/beta the oldest I could go back too was 416.81.  These worked for me.  Make sure you choose a ‘custom (advanced)’ and select to ‘perform a clean installation’.

Hope this helps

Interesting. I have much older than that, 373.06
I’ve mentioned it before. I’ve been a bit surprised to see how little our community discusses driver versions.
Maybe time for a update for me ?

Thanks for the heads up @sliderpoint and @toxie

I get this error with an AMD card. I have also started noticing that it is most frequently with Bally Williams DMD games, Stern games seem to be less problematic. For example I can’t stop and restart a BW game without it crashing the majority of the time, but with Stern I can and even edit the table without it crashing.

Interresting! The only difference between BW and Stern when running a table is VPinmame (emulation), right? VPX doesen’t care about the brand, or does it?

Played TAF yesterday several times without any errors. Launched it from VPX directly and also through PinUp Popper. Today I can’t get it to launch through PinUP at all, just gives the compile error (nothing else). Launches ok from VPX directly.

About NVidia drivers, you can find all old versions here:

I personally had really bad stutter with 416.xx version so reverted way older ones as this historic card quite likely doesn’t benefit from any recent updates. 10- or 20- series is different thing.
