The beta demo ran like dogshit and it looked like dogshit if I used frame gen, and I got a pretty solid PC. Ryzen 7 7800X3D, 64GBs DDR5 ram, 2TB SSD, RTX 4070ti. I had to use DLSS to even hit a 60fps+ target at 1440p, and the even crazier part is I was CPU bound in many scenarios even when the frame rates were around 60. I'd hate to see how bad the game murders lower tier CPUs. My FPS dipped to 56 walking around the main hub area, even a 7800X3D got choked down to sub 60 from a CPU bottleneck. If they would make frame gen not look like dog shit, I might use it, in some games it's serviceable, but not on this game. Frame gen is only decent IF you can get 60fps+ without it, and it might push you into the 150-200fps range, if you need it to hit 60fps, that's going to be a terrible gaming experience.
Weapons I tried out: Bow, LBG, HBG, Lance, CB, GS, GL. I'm mostly indifferent to the changes, or simply don't have enough information about how the weapons will actually pan out once you get into the game further, but early impressions of the bowguns and bow were pretty good. The others felt alright, I don't feel strongly one way or another about them, nothing felt bad to play, which is good I suppose. Some weapons *need* focus mode on pretty much always. The MV for HBG slicing ammo is crazy high, a dedicated slicing gun with decent mag size and recoil with slicing ammo at that MV would be a WMD.
I suspect there will be additional systems in the full game that we didn't have access to in the demo. They let us bring 2 weapons, but I'm guessing we'll be able to run 2 separate loadouts at some point in the full game. That would make weapon combos more versatile, and fit specifically to the user. Like, LS and Lance probably wouldn't use the same skill loadout, therefore combining those 2 weapons would have zero upsides, but if skill loadouts changed when you swap the weapons, there would be no downsides, and which 2 weapons you bring would be a matter of preference.
I hope nobody here carted out to a Rey Dau, you give up any claims to being a MH veteran if you lost to this thing. It's a freaking rath with lightning, it's slow and predictable, I soloed it with every weapon type I tried out above with no issues. In the MH Rise demo, the Magnamalo was actually a pretty tough fight because you were massively under geared, we didn't get a comparable fight in the Wilds demo.
