Little issue with OR 1.4 version..

[dedwa15237]

I had the previous OR 1.3 stable, as I have no issues, whatsoever, as now I am using 1.4 and been getting slammed with errors. All i just simply did is a fresh install, it removed off the 1.3 stuff, and restart new activities, (since I know the 1.4 wont take saved files from v 1.3) and I get this popup, "SharpDX.SharpDXException" error as I will provide the screenioe and zip file.

I am using Windows 7 Full version 64 bit
Intel Dual processor Xeons 3.6Ghz (2 processors)
16GB of memory

Rest of it is listed in my crash report..

Hi Dave,

>Video = NVIDIA Quadro FX 3500 (0.3 GB RAM) (nvlddmkm 9.18.13.745)

Errors like this on the internet point to video card/driver problems.
I don't think the current OR can run with that little video ram.

You could try a different nvidia driver though.

Hi Derek, the NVidia I have shown has plenty of RAM and drivers updated. What I don’t understand that the latest OR 1,3xxx just before the 1.4 was released it works fine. Made it through without a hiccup. Now with 1.4 it started to spew errors. Oddly I just recently replaced the NVIDIA GTX550Ti ( with 3GB of RAM) but it’s much older than the advanced Quattro card it works like a charm with v1.4 OR. I am still scratching my head. Why? I assume it has to be the OR source code issue with reading the Quattros

Thanks
Dave

1.3 did not use sharpdx, it used MS dx.
Sharpdx needs more memory than the quattro card has.

OR reads the quattro fine as shown by

Video = NVIDIA Quadro FX 3500 (0.3 GB RAM) (nvlddmkm 9.18.13.745)
Display = \\.\DISPLAY1 (1920 x 1080, 32-bit, primary, 0 x 0)

Note quattro has 0.3GB ram
550ti has 3GB ram

Checked and chocked out the Quattro, plopped the 550TI I have, and "loaned the GT740SC with 2GB memory"... flawless.. Errors poofed and vanished.. Thanks for helping out.. Should make notes that older vid cards like Quattro will not work.. (under 1GB I mean) with OR 1.4 update.

Thanks again..

Thanks for this useful feedback. I've updated the details on the website to reflect that 0.3GB graphics RAM was not enough.
Would be nice to establish a definitive minimum though.

Video = NVIDIA GeForce GT 430 (1.0 GB RAM)
Works fine.

Anything above 0.3GB--> to 1GB or more will work fine.. Below 0.3 will not.. Like an instance, a 256MB or 512MB video card... I have a 512.. so 512 is calculated as 0.3GB..
