No motion Blur, No Bloom, Lamps aren't Customisable

[Vasey105]

After launching GMod for the first time in a long while, I realised that I couldn't have Shadow Detail any higher than Medium, and I couldn't enable motion blur. Then I also realised that lamps wont work properly in the sense that changing their settings doesn't make a difference and lamps still show the same bland white and bloom simply makes no difference at all. And then to add to that, Super DOF doesn't work, either. I recorded a video to show:

So I looked up a solution, and got as far as fixing the motion blur and shadow detail issue by entering: mat_dxlevel 95 into the console. But with that activated as soon as I try to spawn a lamp the game closes. There's no error message or non-responsiveness, it just closes. I thought it might have something to do with my excessive amount of addons, 350+, so I unsubscribed from all of them but the problem still persists. Any help is appreciated.

Specs, if they're needed:

[B]Processor:[/B] AMD FX(tm)-4100 Quad Core 4.0 Ghz

The problem still persists with that entered.
The game also closes when I turn on my flashlight.

Try putting -dxlevel 95 in your startup parameters. 98 is broken iirc

That worked, thanks.
