Free Download Car Racing Games For Pc Windows 10 64 Bit

WhenI run Viper Racing (you can get a copy here: links to abandonware are forbidden.) patched to 1.2.3 (via 1.2.1, the 1.1 patch won't work with my version ever), it boots, then shows a pop-up window titled "Our Apologies" and "Your video card returned an error. Are your video drivers up to date?"

I'm suspecting it's an nvidia driver problem (not surprising how their 'way it's meant to be played' is broken in most cases to the point where people blame Windows) as it works on RadeonHD6 here without any wrapper on Windows 7. v1.0.

Ironically some games that were broken on my previous computer now work though, e.g. Plane Crazy, Sports Car GT (Glide), Shadows Of The Empire, Wipeout 2097... some with more specific fixes though! I've got hundreds more games to run through though, so I'll be raising any more in here too. Plus any fixes I generate!

So you have to place DDraw.dll and D3DImm.dll into the Data subfolder.

Unfortunately the current dgVoodoo version does not work with it because of a small incompatibility with MS DX5.

I've fixed that and the game now works beautifully. Will be included in the next version.

Dege, I think once I've finished re-installing games (may be a few months haha!) I'll post a thread for you with all the games I have issues with (might test run them on ATI based PC at work too), so you've got a list of things to have a play with. They're mostly racing games, mind you...

It's a bug in the video card detection routine that triggered when video memory size reported by DirectDraw is close to 4Gb. Nascar Heat is built on the same engine and exhibits the same problem. I've managed to patch the Nascar Heat to fix this bug, and it looks like this patch can be applied to the Viper Racing as well. For the patch details please see my answer at superuser.com. If it doesn't work for you, post here or drop me a PM, and I'll try to help.

The problem seems to be pretty similar to the Nascar situation in that the reported vram is to big to fit into a 32 bit integer causing a change in signedness. Since a negative number is obviously smaller than the 4 MB minimum requirement the benchmark refuses to run. 3dMark 2000 uses these functions to detect the amount of video memory:

All of the aero analysis I've seen shows cars in an optimal (closed window) state, yet production based cars are generally required to run with at least the front side windows open. So it would only make sense for GRM to have a discussion about what would be the best way to minimize drag on a car with open front side windows?

Purely as an interesting data point. Our one racecar(truck) has no side windows and no rear window(well, we cut the back roof off a sedan). Wind hits the driver in the back of the head. There is a lot of swirling going on inside the cabin. We need interior yarn testing.

But for a truck with a much smaller slider opening in the rear window, it seems to draw air neatly through the cabin while also reducing interior turbulence. I've also seen some race cars put holes near the base of the polycarbonate rear window, presumably to similar effect. What that actually means for overall drag though, I have found little discussion and no data.

Conversely, redirecting high pressure air to low pressure areas has been used to reduce drag elsewhere too. I'm namely thinking the 'air skirts' being used on many (most?) new cars, to redirect air from the front of the car through a slit behind the leading edge of the front fenders. Could similar benefits be achieved for the cockpit, drawing from there or the base of the windshield?

But I wouldn't take air from the base of the windshield. Since you already have high-pressure air there, you would be losing some downforce by removing that high pressure area. Sucking air from under the hood or from under the car would be ideal, but could be difficult to achieve. I think you would also need a pretty big fan (I'm thinking multiple box fans) to maintain this pressure. I'm not sure how much and how feasible it would be.

Modern cars are designed to have lower drag with the windows up as noted. Required windows down/open is more draggy and introduces flow to the cabin that generally creates a harmonic resonance (a low frequency noise most often). Try to imagine the air coming in at the back of the windows and swirling around toward the center and back toward the windshield, then out toward the a-post. Some air exists, a lot stays contained in the swirling vortex. The cabin pressure is lower than ambient due to high speed air flowing over the a-post edge, this can be noted by the vents usually having some flow even with the fan off.

For drag reduction, you should try to deflect the air at the a-post further out board to reduce the inflow at the back of the window and keep it mostly attached to the sides. This will generate its own drag but best case scenario the increase is less than the swirling/vortex flows in the cabin. It will still be noisy and low pressure.

Adding to this thread to ask related questions. My RX7 (1st gen) has open door windows per ChampCar rules. Back windows are lexan. We can put some holes in the back window to help with ventilation, which is ultimately what we are after. I had some thoughts about putting a few 2-3" holes (whatever the rules allow) for ventilation.

I agree with the other comments that a high pressure builds inside the cockpit for open window race cars that helps to "push" incoming air out (to some extent). I am not an aeronautics engineer, but it makes sense. This topic was covered on an episode of Myth Busters TV show debating pickup trucks travelling with tailgate up or down, and with windows up or down.

Missed your post, but wanted to give you some info. Putting holes in the top of the rear glass will draw the most air thru the cabin. It may hurt rear downforce if you have a spoiler or low mounted wing. The low preesure at the top of the rear glass is about as low as you will get on the upper body (front of roof is lower). Generally the air exiting the top of the rear glass can be used to help energize the flow down to the deck lid.

For hole shape, circular is the easiest but not the best. For max effect long slots across the width will be better. A slot with tapered edges is best. Think of it like cutting straight back to front (horizontal) instead of 90degrees to the glass. Leave some material every 10 to 12 inches to keep the lexan from flexing too much. 1/4 to 1/2 wide slots should be plenty. You can tune the opening area with tape if you have too much flow but probably wont need to.

I'm not the biggest fan of Mario... having spent a significant amount of time "debunking" his posts over the last couple years to some friends of mine... I tend to avoid using superlatives with his work.

I happened to notice some kind of deflector thing in front of the side window openings on some of Sierra's Pikes Peak entries. I don't know what exactly it was supposed to do, or if it did it, or if anyone ever did any testing. Crosskarts don't exactly put a high priority on drag reduction.

I've been thinking about this lately because the removable hardtop on the Miata tends to create a high pressure area that pulls a lot of air into the cabin windows down and makes it difficult to record audio even at autocross speeds.

It's interesting that my 8th generation civic coupe, which has long doors and windows, and no opening back windows does not get the high speed buffeting and resonance that I have experienced in sedans and wagons.

We began working with SHIELDS in the fall of 2010, after several failed attempts with other potential vendors, at developing a windshield for our electric utility vehicle, the Firefly ESV. Other suppliers were not able to achieve satisfactory clarity of consistent shape with the radical curvature and size windshield that we needed. Not only has SHIELDS surpassed all our design specifications, they also developed a frit (border) application process (saving us labor cost), provided their SUPERCOAT coating which exceeds our scratch resistance requirements, and constantly delivers a quality product on time. Working with SHIELDS has been a distinct pleasure, and we wish all of our suppliers could perform as they do; they are a quality group of people!

After almost 10 years with Shields, service has been nothing but excellent. Not only are they a vendor to Intercontinental Trophy Cup but they have also become close personal friends. What sets them apart from other manufacturers is their eagerness to take on dynamic and different projects when others choose to stay inside the box. They have provided windshields, stock glass replacements, and trophies for us over the years and we look forward to continuing the relationship with our new racing series.
