At runtime only? It would be extremely good

UPD: in Vice City just need to disable the game frame limit (in game menu - video options). And ResX\Y=-1 if using GTAVC.WidescreenFix.

I suggest option for wrapper set affinity mask for game. Many games can work only on one or two cores (or 2 or 4 threads if HT is on).
For example i noticed from the game Blitzkrieg 2 (which not runs if not start with /affinity, because this game not see more 6 threads) if i start Blitzkrieg 2 with /affinity 1 game start but perfomance dramatically bad (because used 1\2 from one physical core). If /affinity 3 (1 + 2) that better but have stutters (because in reality game runs on 1 physical core). If /affinity F (1 + 2 + 4 + 8 = F) that much better (because game use 2 physical core). If /affinity 6 (2 + 4) game can (50% chance) not runs (something with threads between physical cores). F - best choice with HT.

So i tryed newest version with dungeon keeper D3DImm and DDraw. Games lunches. Intro Works fine menu works fine. But when you start a game. The game crashes.

Tryed Dungeon Keeper Gold with 3d3 patch

Deeper Dungeon and the Original with D3d Patch 😀

I don't have a clue when I will have a new version, so I release the current state as a WIP (mostly fixes for problems I encountered):

=========================
WIP95
=========================

Changes compared to v2.82.3:

• Fixing vertex clipping in D3D5 (regression) (Jet Moto)
• Refactoring a lot of code in DDraw to implement resource sharing, to be compatible with MS DDraw (flashing screen in Colin McRae Rally 2)
• Fixing DDraw clipped cursor problem (like with the config app of game Driver)
• DD/D3D/8/9 frontend objects consumes less memory
• Removing paletted texture format support of the GF9800 virtual card
• Fixing a potential D3D8/9 swapchain leaking bug
• Implementing some missing validation in D3D Draw methods
• Fixing a clip coordinate space bug with sst origin lower left in Glide3+
• Adding a new option DirectXExt\D3D12BoundsChecking (try it if you run into a GPU crash with D3D8/9)

Some explanation for DirectXExt\D3D12BoundsChecking: it's for cases when a D3D8/9 game accesses the vertex shader register array in out-of-bounds (OOB) way (buffer overrun).
It causes a GPU crash with dgVoodoo by default. The fix should not have an option, because D3D8/9 specs are clear about this case, so it should just be implemented in dgVoodoo.
However, according to my profiling, the implementation of bounds checking can cause 8-9% performance drop in certain cases wih certain games. That's a lot.
I cannot optimize it away, the (certain) needed D3D12 call is simply too expensive for extreme frequent usage, at least with my NV driver (did not tested other GPU's).
I only know of 2 games requiring this, The Witcher and Bound by Flame, so I decided to make this feature optional. Enable it if your GPU crashes with the D3D12 backend.

For the time being, I think I'll release a new patch version, 2.82.4.
I'm (very slowly) working on other under-the-hood developments and ran into some bugs for which a fix worth to / should be released.

I backported some fixes to the lates release, that's what 2.82.4 is about:

=========================
2.82.4
=========================

• Fixing DDraw bugs (Konami Collector's Series: Castlevania & Contra, Blackstone Chronicles)
• Workarounding a DDraw internal resource sharing problem
• Fixing DDraw clipped cursor problem (like with the config app of game Driver)
• Fixing D3D5 vertex clipping (regression) (Jet Moto)
• Removing paletted texture format support of the GF9800 virtual card
• Fixing a potential D3D8/9 swapchain leaking bug
• Fixing a D3D9 frontend bug (The Mark)
• Fixing stenciling without a stencil plane in the D3D12 DX backend (Test Drive Unlimited 2)
• Fixing potential descriptor corruption with sRGB textures in the D3D12 DX backend (Test Drive Unlimited 2)
• Some minor refactoring in the DX frontent/backends
• Fixing a clip coordinate space bug with sst origin lower left in Glide3+

I release a new version with the latest fixes and also updated WIP95:

=========================
2.82.5 / WIP95.2

Now CMR2 flashes really badly on 2.82.5 after changing in-game resolution (Options -> Graphics -> Advanced Graphics -> Display Mode). I'm using SilentPatchCMR2 and flashing only occurs when I set "Window=0" in SPCMR2.ini (I prefer forcing windowed mode through dgVoodoo because SilentPatch "Window=1" performs horribly).
