Windows 8 Laggy In-Game Play

[outbreak525]

Hello,
I have recently upgraded to Windows 8.
Unfortunately I upgraded before finishing Black Mesa.
Because when I go in to play Black Mesa, it now runs incredibly slow.
I saw that somebody else here had the same issue with Windows 8, and he fixed his problem by ‘Running as an Administator’
I have already tried to run steam as an administrator and play Black Mesa, and the problem still persists.

The warnings that come up in the console are:

Error! Variable “$surfaceprop” is multiply defined in material “models/props_c17/oil_drum_chunks001a”!
Attempted to create unknown entity type Default!
NULL Ent in UTIL_PrecacheOther

Performance warning: Merge with ‘weapons/w_glock_lh.mdl’. Mark bone ‘ValveBiped.Bip01_L_Hand’ in model ‘humans\hassassin.mdl’ as being used by bone merge in the .qc!

and

Attempted to create unknown entity type Default!
NULL Ent in UTIL_PrecacheOther

Please let me know if there is a fix to this Windows 8 problem! And if so, when can I expect a fix?
Thank you very much.

windows 8 is very bad for gaming try downgrading back to windows 7

I went to Control Panel > Troubleshooting > Programs and set it so Steam opens as it would on Windows 7.
However, it still got extremely laggy during the end sequence, and the first time the fast stealthy pistol shooters came in. Almost unplayable.
Upon opening the console there were many errors.
The rest of the game ran smooth.

Maybe you need a new laptop. However, every time there’s a new iPhone, people line up worldwide, waiting outside Apple stores, sometimes for days, to be among the first to get it. It’s the height of stupidity; the phone isn’t any different a few days later. Furthermore, if one waits about a year, it gets cheaper and the bugs in the darn thing haven’t even been discovered yet.
