So I recently installed The Penumbra Collection from GOG, started Overture, but after loading the game gives a white screen, I googled it and it said to disable post process effects, I did it and it worked but the game didn't look good, so I messed with the settings, so end result, disabling bloom but leaving all the other post process settings intact would also fix the problem, but I don't want to disable bloom (the only settings I disable/reduce in any games that I play for better performance are shadows, ambient occlusion, motion blur, resolution and occasionally v-sync, all other settings like textures, post fx effects (depth of field, bloom, specular etc) are maxed out, and games run pretty well (10-60 fps). There is another game that was a big problem: ParaWorld
The game's textures used to continuously flash (sometimes the entire screen too), at some specific angles the game would become stable, but would start flashing again, I loved this game but could never play it because of this problem, but when the VERY FIRST time I installed it (4-6 years ago) I remember the screen or textures wouldn't flash, and was going through chapter/mission 4 when my HDD died, and I had no idea what drivers I had installed, so I eventually after getting a new HDD and installing windows (also a few years ago), I got the latest supported drivers for my intel graphics card (generic intel drivers apparently) and since then the ParaWorld flashing problem started, so after months of failed attempts to fix it, I eventually gave up and uninstalled it out of anger.
But today, after the Penumbra graphics problem I decided to install the OEM drivers for my graphics card (took nearly 2 years to find them but found it today through driver identifier) it was version 8.15.10.2281 (modified for my toshiba model I think), so I uninstalled my current graphics drivers (generic v8.15.10.2993), and installed the older OEM one and first thing I did was install ParaWorld and to my surprise, the game worked like a charm, the texture/screen flashing problem was gone and only on rare occasions the flashing happens. I had high hopes for Penumbra - Overture, and the white screen was gone alright, but there is another problem now:
This is what the game looks like now with the OEM drivers.
Now on with the system problem, my graphics card supports DirectX 10.1 and when the generic drivers (8.15.10.2993) were installed my DDI version in dxdiag was 10.1, in the intel control panel it was 10.1 and in the windows experience index it was 10.1, but now with the OEM drivers (8.10.15.2281), it just shows my DirectX version as 10 (10.0) everywhere, intel control panel shows 10.0, dxdiag DDI version is 10, and windows experience index shows it as DirectX 10, I couldn't find any clues on google so I though I'll post it here, because you guys know more about this stuff than I do
. My thoughts are that after I finish paraworld I go back to the generic driver, but what do you guys suggest, should I go back to using the generic drivers or should I stick with this OEM one 
(cuz I have a feeling that this driver is gonna cause more problems than fix them) and I have yet to test other games, but my main concerns are ParaWorld, Penumbra and my system not using the highest DX version that it used to. 
in advanceEDIT: I forgot to mention that in windows experience index my scores with the generic drivers were:
Desktop performance with windows aero 3.8
3D business and gaming graphics 5.2
and now with these OEM drivers it is:
Desktop performance with windows aero 3.9
3D business and gaming graphics 5.1
, but the problem with Penumbra is still there.
, It is about the graphics, or more specifically, textures, for many games (but the one I need help with is ParaWorld). On my old laptop (Intel Core i3-380m, Intel HD Graphics Arrandale, 2 GB RAM (1.86 GB RAM usable), Windows 7 Ultimate x64), in the graphics control panel I set the texture quality setting to 'Quality', Anisotropic Filtering to 'x16' and Vertex Processing to 'Default', and the textures for many games would become crisp, in Paraworld, this was noticeable on tree leaves, rocks and buildings, and it looked like a game from 2010-2014. But on my new laptop (HP Pavilion dv7-6b55dx Entertainment PC, Intel Core i5-2430M 2.40 GHz, Intel HD Graphics 3000, DDR3-1333 8 GB RAM, Windows 7 Ultimate x64), the settings in the graphics control panel are the same, but the textures look like shit, like the game was indeed made in 2006, the tree leaves are very low res and look pixelated textures that were scaled up, here are the screenshots:
