RoyBatterian (mod author of the FNV 4GB Patcher) has suggested not to use the Heap Replacement in FNV Stutter Remover. It is buggy. He suggest to just use the sheson NVSE heap patch. He also included his own Heap Patch in the FNV 4GB Patcher and is more efficient than NVSR's Heap Replacement and using the Heap Replacement in NVSR overwrites Roy's Heap replacement. So the Heap Replacement should be turned off in NVSR.
Dirty Weasel also confirmed this in his brand new FNV Modding Tutorial for the FNV 4GB Patcher (yes, he is back making Bethesda Modding Tutorials);
