From the look of it, your graphics card is corrupted. plus Wiremod can’t fix anything, as it is a addon, not a part of the source engine’s code. you will need to upgrade to a better card. as some people say, as technology advances, programs will advance with them. so far there has been 1 major graphics problem within one year of writing this. this rendered the pixel shading differently then before, but i doubt it has anything to do with that monstrosity of a screenshot. (No Offense) Sadly, replacing your graphics card will cost approximately 200-400 USD, depending on the model. But the strength, durability, and demand for said graphics card determines the model’s price. a good graphics card
such as a Nvidia GeForce, or An ATI Radeon, will cost more than the above price. 650-700 USD for a lower class-high end graphics card, and 1,000+ for a elite class-high end graphics card.
The reason I said Lower Class and Elite Class is that i rate Graphics cards and CPUs At different Subcategories within their own category, Low End, Mid End, High End.
Low End Needs to be avoided, otherwise you’ll get worse results then you want.
-Lower Class (Obsolete)<-Does this not tell you ‘Not to Buy it’?
-Economy Class(Good for web usage, not compatible with recent 3-D games, such as HL2, COD: Black Ops, ETC. ETC.)-Why would you want to buy this?
-Elite Class(Good for web usage, flash Games)-Why would you want to buy this?
-Lower Class (Good for web usage, flash games, some 3-D games.)-Why would you want to buy this?
-Economy Class(Good for web usage, flash games, capable of gmod, but has some lag with SWEPs, such as ife.NERV’s Customizable Weapons Pack.) price range 300-499
-Elite Class(Good for web usage, flash games, works well with gmod, some frame lag with nuclear weapons.) Price Range 500-649
-Lower Class (Good for web usage, flash games, gmod runs smoothly.) price range 650-799 USD
-Economy Class (Good for web usage, flash games, gmod runs smoothly, Multi-Tasking is Possible.) price range 800-999 USD
-Elite Class(The best of the best, capable of anything. something you’d find in a Alienware.) price range:1,000+ USD
Though, it could be a corrupt driver. roll-back to the last driver you installed to ensure this isn’t a Firmware-Hardware conflict.
I Hope this helps you.
