Has anyone tried to replace SSE4 in the game with their own implementation?

I play the game on Win 7 Phenom II. Red Dead Redemption 2 (1311.23). I was unable to start the game with sde. I have solved the problem with Cheat Engine. Has anyone tried doing this?

lol I guess but really dude? it would be easier to just get a better cpu, even if you get it to work I feel like this could potentially wreck performance.
you might be able to inject an exception handler that intercepts the illegal instruction exception and either manually sets the regs to what they should be or dynamically applies patches.

too late for a new processor, already finished the main story. I can't say that performance is great. According to the benchmark

Code: Select all

Frames Per Second (Higher is better) Min, Max, Avg
Pass 9, 7.564877, 41.837738, 29.844543
I set textures and lights to ultra, but the instructions that I replaced are more about lighting and draw distance. This is what usually broke when I replaced pshufb, pmulld, pcmpgtq, ptest.

Can anyone manage to run intel sde with rdr2?

The same solution for the Detroit Become Human demo. There is at least one bug with dialogs.

have you tried a generic approach?

Imagine when Intel Celeron G550 which is 2.7 GHz 2 cores, have SSE 4.1, while AMD Athlon A8-3870K 3GHz with 4 cores doesn't. Would I get a "better cpu" by buying Celeron then? XD
