This causes a 20-30% performance hit because your CPU is translating every complex math call into simpler math in real-time. However, on a quad-core i7-2600K, the game runs at a stable 45-55 FPS on Medium settings.
on an older CPU, you were likely met with a frustrating wall: "Requires a CPU that supports AVX2 and FMA instructions." For owners of legendary but aging processors like the Intel Core i7-3770K or the AMD FX series, this feels like an artificial barrier.
While no patch completely removes the AVX2 requirement (as it is baked into the core physics engine), introduced a fallback render path for specific GPU-culling tasks that previously relied on AVX2.
Here is a guide on how to apply the fix.
