@siro20, @iiv3, I tried to merge this, but I'm afraid this still needs additional work.

When I tried to run d3dretrace --pgpu ... on Windows it immediately hung.

Looking at the source code, snippets like

while(query.ids[GPU_START]->GetData(&gpuStart, sizeof(UINT64), 0) != S_OK) {}

look wrong in a few ways:

• One should use D3DGETDATA_FLUSH, to ensure the commands are actually flushed
• One should check for S_FALSE, to avoid deadlocking on errors

See https://docs.microsoft.com/en-us/windows/desktop/direct3d9/queries for more info.

There are some matters of code style, but that I can gloss over for now. But this needs to work minimally well not only on WINE but on native Windows before I can merge.

It's not too hard to fix it myself, but I don't think I'll have the time now, as I'm looking for the low hanging fruit PRs I can merge without too much manual intervention.

I'll fix that possible deadlock and check if I can make it more stable.
I can only test on WINE, but we will work with the community to test it on Windows, too.
