I hope CryAdam or CryTom will see this.
I have noticed that hires textures are not working in MP only in SP. But whats more interesting it is not working in SP also when i came back from MP. If i want play with hires textures in SP i must lunch the game again in MP textures never worked for me. Some pictures to explain:

textures in SP after lunching the game


textures in MP


textures in SP same spot as picture one after returning from MP


Hires textures pack was enabled all the time.
In my "game" and "autoexec" cfg files i have "sys_highrestex = 1" but it didnt help at all.
"sys_highrestex" comand in console is not working its unknown for the game too.

Guys could u post if it is the same for u or not and if someone dealth with this problem and how.

I would like to play MP with hires textures thanks.

Due to lack of no real anticheat protection such as PB, this kind of modifications have been restricted from MP, because people altered MP files to cheat.

I think it's not enabled in Multiplayer

That doesn't explain how the high res textures got disabled upon returning to single player mode, despite having "High Resolution Textures" enabled the whole time.

Ok then DX 11 is not enablebled in MP too?

DX11 is disabled aswell

no DX11 is enabled partly i think.

Yes, it is partly enabled (e.g. the DOF effect, tried it myself). Though Tesselation seems to be disabled.

Wow, I've yet to buy Crysis 2, but it sounds like the multiplayer and the game is a mess.
