Hi, the title might be a little misleading but I am not trying to compare those video cards. I am a very basic user of 3ds Max 2008. I do not have a video card other than the integrated video of an asrock wolfdale 1333-d667 (which is an intel 945). I got in my hands a GeForce 7900 GS and a Quadro FX 4500. I though it would be nice to see how faster would 3ds max work with these cards. I had a very basic animation/scene where I could do tests. With my Intel card, I render a single frame from my animation and it took between 25,1 and 25,5 seconds to render. Next, I installed the GeForce 7900 GS, drivers and all, and the same frame took 25,0 to 25,3 seconds to render. I thought maybe 3ds max DOES need a quadro to see improvements, so I installed the Quadro FX 4500 uninstalled GeForce drivers, installed Quadro drivers, started 3ds max 2008, the software detected quadro drivers, installed 3ds max performance driver, restarted max and checked if it was using OpenGL, DirectX or Software rendering drivers but it actually used the performance driver which uses DirectX. Then I opened animation file and rendered the same single frame: rendering time 24,7 to 25,1 seconds. I do not know what am I doing wrong but there should be some difference in rendering times, right? or perhaps I need a scene that actually uses some OpenGL or DirectX commands/instructions. I use: Windows XP Professional 32-bit Service Pack 3 fully updated CPU: Intel Dual Core E2160 RAM: 2 GB DDR2-667 (2x1 GB) Motherboard: AsRock Wolfdale 1333-D667 Latest BIOS according to AsRock web page. For GeForce 7900 GS: 182.50_geforce_winxp_32bit_english_whql.exe For Quadro FX 4500: 182.46_quadro_winxp2k_english_whql.exe 3D Studio Max 2008 (It is NOT original, i.e., it is a cracked version.) Rendering Engine V-Ray Adv 1.5 RC3 (also cracked version) Scene: It has an Explosion atmospheric effect in the middle of the effect. There is a plane with a diffuse map applied to it and the same map applied to the displacement slot. There is an omni light. V-Ray is configured with the most common modifications you can make. I also tried rendering the scene with each video card using different display drivers OpenGL, DirectX, software and performace (in the case of quadro) but the results where the same. Maybe the benefits can only be seen in the UI of 3dsmax and not in the rendering itself, o maybe the difference can be seen if you have a trillion polygons and thousands of objects and meshes and stuff. I also tried the rendering on a different machine with Windows Vista 64-bit, 2 GB RAM (i don´t know why have a 64-bit OS with only 2GB but it is not my computer) with a GeForce 9800 GTX+ and got the same results, but if I used DirectX 10 as display driver, the viewport became impossible to work!!!. I have seen benchmarking being done and I think I know the difference between these cards but it just blew my head when I got the results from this probably invalid comparison. Thank you very much for all your comments on this topic!!!!
