I'd love to hear some advices regarding this graphical problem

[Ashy]

Since the last update,my graphics have gotten worse: I've tried doing a research both on these forums and esreality but it seems i'm unlucky

First picture:
the "mega zone" has that incredibly annoying highlightened,blurry part right in the middle of it, and I see annoying "blurs and spots" on walls and floors, for example the one right next to the weapons left sided bar.

Second picture: very noticeable blurs and spots on the walls,box-shaped lights on the left part,and, most of all, very poorly-drawn textures on countours/outlines, especially on the stairs steps and lower "bridge part"

So far I've tried modifying these cvars:
ignorehwgamma
mapoverbrightbits
overbrightbits
picmic (it quite helped since the blurs are more box shaped but the overlighted effect still persists)
contrast
gamma

..but unfortunately it didn't work,so here I am bothering you,sorry about it.

My cfg:

The pc spec,in case is needed,is:
intel duo e8400
nvidia 8800gt
2gb ram

I wish I could find the settings to achieve clean graphics,thanks for reading this

EDIT: I included the pc specs as i sometimes get some weird lack of smoothness in the game: it feels like a light fps drop,yet the fps is always at 125,and the connection is quite good,I really have no idea what could cause that,I was afraid it might have had something to do with my pc

change your lighting settings

[Ashy]

that was quite vague,but thanks anyway: could you please tell me exactly what i should change?

[*sp0nger]

options -> advanced -> video options -> lighting model

also update your drivers

[Ashy]

Tried updating my drivers,nothing changed

Then I tried doing as you suggested,here are the results,starting from "Lightmap":

As you can see,it gets even worse than before, I didn't think that was even possible

is that 16 bit color? if so, try 32 bit?

[Ashy]

seta r_colorbits "32"

this is the cvar in my cfg,is it what you mean?

[barbarossa]

i was just guessing. don't know if it is to set somewhere else too.

I'm having the exact same problem now. I tried reinstalling the plugin to see if the graphics would reset, but it seems as if it saved my settings. I'm kinda stumped on this guys.
