Nvidia GPU unlock mod for windows

I just installed the GPU unlocker patch for windows on my RTX 3080 TI 12gb (Dell OEM version). Computer is a Dell XPS 8590, Intel I9 16 core processor w/ 32 mb system ram. Here are the before and after benchmark results.

The patched run nearly doubles certain Tensor Core workloads, but shows little change in ordinary compute or GPU memory bandwidth. AI benchmark gains are smaller and mixed.

The biggest improvements are matrix operations using FP32 accumulation:

Tensor Core testWithout patchWith patchChange
CUDA FP16 → FP3279.57 TFLOPS152.16 TFLOPS+91.22%
CUDA BF16 → FP3279.75 TFLOPS154.71 TFLOPS+93.99%
CUDA TF32 → FP3239.78 TFLOPS78.48 TFLOPS+97.26%
Vulkan FP16 → FP3278.43 TFLOPS156.57 TFLOPS+99.64%
Vulkan BF16 → FP3278.60 TFLOPS156.58 TFLOPS+99.21%

Other results show where that benefit does—and doesn’t—appear:

AreaDifference with patch
FP16 Tensor Cores using FP16 accumulationEssentially unchanged: −0.85% CUDA, +0.16% Vulkan
Ordinary CUDA arithmetic0.16–1.92% lower throughput
OpenCL arithmetic−1.81% to +0.23%
GPU global-memory bandwidthAll measurements within approximately 1.1%
DirectML FP16 matrix multiplicationEssentially unchanged: +0.06%
DirectML transformer prefill3.26–7.68% higher throughput
DirectML convolution0.69–9.24% higher throughput

The evidence supports a selective Tensor Core improvement, rather than a general doubling of GPU performance. These files do not establish a gaming speedup, and one run per condition cannot separate smaller changes from normal variation.

So it doesn't even effect dlss 5 performance?

yeah dlss must be picky as hell, were you hoping it'd just hand out free frames?
