Moto GP URT3 Bloom support requires supporting D3DPTEXTURECAPS_NONPOW2CONDITIONAL
As quoted by Dege
It needs non-pow2 textures for the bloom effect but misinterprets the D3D9 capability bits when checking out if they are supported. It works only if the 3D device supports them conditionally, but not when they are unconditionally supported (like on modern hw).
Dege made a patched game binary available for this, but I imagine it should be doable from the wrapper too by emulating `D3DPTEXTURECAPS_NONPOW2CONDITIONAL.
Yes, it is certainly possible to change the caps in this way with a wrapper. However, this may cause issues with other games so it would need to be an optional caps change. It looks like that option was added in DX6 and is supported through DX9.
What version of DX is the game using?
This one is Direct3D9
It seems nvidia had started to remove this cap by the point of Geforce 6, or atleast the drivers after FW 85.xx
However, this may cause issues with other games so it would need to be an optional caps change.
It shouldn't, also i was too quick to assume it was just the NPOT cap missing, it also needs D3DPTEXTURECAPS_POW2 which is also removed on modern hardware.
If this issue has already been fixed with a patch why do you need a wrapper with this fix?
I did create a test build with a fix for this. I added a hidden feature you can add to the ini file called SetPOW2Caps.
Force caps change: 1 = force D3DPTEXTURECAPS_NONPOW2CONDITIONAL, 2 = force D3DPTEXTURECAPS_POW2, 3 = force both, 4 = remove both
Here is the test build: dxwrapper.zip
Let me know if this works.
BTW: I could just always force both. But some games may check if D3DPTEXTURECAPS_POW2 isn't there because the games may require non-POW2 textures. All new video cards support non-POW2 textures and it is likely that newer games use/require this. However, adding D3DPTEXTURECAPS_POW2 tells the game that the video card doesn't support non-POW2 textures.
I added this option, but I changed the values because I think forcing both caps is the most common case. Here are the new values for SetPOW2Caps:
- = force both
- = force D3DPTEXTURECAPS_NONPOW2CONDITIONAL
- = force D3DPTEXTURECAPS_POW2
- = remove both
Thank you so much. this fixes a visual bug with the game Europa 1400
can you demonstrate?
using dxwrapper with the setting
here's the full breakdown of the bug and a patch we worked on.

this was also an issue when using wined3d implementation of d3d or even dxvk on linux+wine or even on native windows.
my current setup with dxwrapper for d3d8 -> d3d9 and then dxvk for d3d9 -> vulkan on linux with wine seems to work well. haven't tested natively on windows yet tho.
doin a bit of digging, the 4 listed caps are present on Geforce 4 and lower
Geforce 6+ do not have the conditional NPOT cap,
