Hello

Right now I want to test what my old x1650 card can do better, D3D9 or OpenGL rendering, so do any of you guys know a software that can help with to acomplish that? Kind of a benchmark?

Thanks in advanced

PS: I'm running Windows 7

Here are 2 tools that allow you to test and compare both Direct 3D and OpenGL:

FogCity measures the Direct3D and OpenGL speed. (quite old, but it still works with Windows 7, free & portable)

Fraps is a universal Windows application that can be used with games using DirectX or OpenGL graphic technology. In its current form Fraps performs many tasks and can best be described as:

Benchmarking Software - Show how many Frames Per Second (FPS) you are getting in a corner of your screen. Perform custom benchmarks and measure the frame rate between any two points. Save the statistics out to disk and use them for your own reviews and applications.

Furmark looks kind of dangerous =) geeks3d.com/20091209/… – Fladur Jan 24 at 20:45
@Fladur - Looks more like some overclocking gone bad. but then, video card benchmarking is not for the faint at heart. it ain't solitaire, you know :) – Molly7244 Jan 24 at 20:48
I know, just kidding xD. I damaged a GeForce FX5500 xD with 3D Mark xD – Fladur Jan 24 at 20:50
tss ... nonsensical downvotes from some anonymous lackwits. – Molly7244 Jan 24 at 21:42
Sorry to hear that u.u – Fladur Jan 24 at 23:02

Games and most benchmark programs will not work, it is like comparing the acceleration of two different cars under two different sets of circumstances.

Games for DirectX will use one set of features and if they have a port do OpenGL, it will probably have a few different textures / feature and run differently - again, comparing apples and pears! (or whatever the saying is!).

What I would recommend instead is programs that are actually designed for both - such as 3dStudio Max (You can download a demo), and try rendeing a simple scene on either and time it.

You should be able to compare D3D and OpenGl performance on the same card.

Find a tool that allows you to choose the rendering engine - Unigine Heaven for example - run it in each mode and compare the results.

You can download it from here

Just had a very quick look and I do not know for sure, but what I tried to say in my answer is this is a very awkward thing - DirectX and OpenGL are quite different. It is possible that they take advantage of a feature in one API that doesn't exist in another, so one may produce higher FPS/benchmarks but the other may look a lot better. – Wil Jan 24 at 21:55
@Wil - A properly designed benchmark program should take care not to "cheat" in this manner, or at least tell you that it is. I worked in 3D graphics for a while in the 1990's to early 2000's so I know it's possible. – ChrisF Jan 24 at 22:31
@ChrisF, But, I thought most benchmarking software is designed to test the same software on different hardware... OpenGL v DirectX is another kettle of fish, even if it doesn't cheat, there are still things that one is better at than the other in certain experiments, so any benchmark will not really be the same as real world usage.... I don't mean to overstep the mark as I never worked with (or really know that much about) 3d graphics, but again, in all my experience, I have seen benchmaring software for various scenarios, but not DirectX v OpenGL. – Wil Jan 24 at 22:39
@Wil - well I'll admit my knowledge is 5+ years out of date, but the whole point of comparing D3D to OGL for a particular scenario is to show which is better so that you can choose what's right for your application. – ChrisF Jan 25 at 8:58
@ChrisF, Exactly, one performs better in certain scenarios, you can't really compare one against the other outright.... e.g. in benchmarks, for example, a Ferrari is faster than a standard car, but a standard car is probably a lot more comfortable... It doesn't mean a standard car is better just because it wins in one area. Something may take advantage of one technology and appear to have a lower benchmark score whilst actually producing a better result. Anyway, I just really do not know enough to say anything more and don't want to argue especially as 3D is not my area... but +1 to you! – Wil Jan 25 at 10:18
