# wine-patches

Various wine patches mostly aimed at improving performance that aren't in wine or wine-staging (yet?).

May require CSMT patches (wine-staging).

### 0001-ntdll-improve-heap-allocation-performance.patch

Improves heap allocation performance by balancing free lists and improving common bottlenecks.

Fixes Guild Wars 2 FPS decrease when it is running for a longer period of time and can almost

double the FPS in big fights (World Bosses, WvW, etc...) by reducing the overhead of the memory

allocator from ~30% CPU time to ~2%.

Don't use the "ntdll-Heap_FreeLists" patch from wine-staging when using this one (they have conflicting changes).

### 0002-ntdll-heap.c-align-everything-to-64-byte-to-reduce-f.patch

Align allocated memory to 64 byte boundaries to lessen false-sharing issues. May increase RAM usage.

### 0003-wine-list.h-linked-list-cache-line-prefetching.patch, 0004-ntdll-heap.c-freelist_balance-prefetch-next-entry-ca.patch, 0005-oleaut32-typelib.c-fix-cursor2-having-the-wrong-type.patch

Potentially doubles the speed at which linked-list can be traversed. Linked lists are used in many places in wine.

Patch 0005 is only needed if you are also using the heap allocation patch (0001).

### 0006-Ensure-16-byte-alignment-of-data.patch

Align data in allocated memory to 16 byte byte boundaries.

### 0007-wined3d-use-SwitchToThread-waits-in-wined3d_pause.patch

Requires: CSMT patches.

Can reduce CPU usage when using the CSMT patchset by up to 50% or sometimes even more. Whether this translates into

an FPS increase or an improvement in responsiveness depends on your OS and hardware (and game).
